为什么Console.Readline没有按预期执行

我有下面的代码来处理。 我在这里的问题是代码运行while循环，而不是等待在行上的inputString temp = Console.ReadLine（） 。 需要帮助了解为什么以及如何修复请。 提前致谢！

/*Banker's algorithm Implementation*/ class Program { static void Main(string[] args) { int n = 0;//number of resources we will be dealing with int proc_num = 0;//Total number of processes to share available resources IDictionary<String, SysProcess> processes = new Dictionary<String, SysProcess>(); IDictionary<String, int> MaxR = new Dictionary<String, int>();// maximum available resources IDictionary<String, int> avail = new Dictionary<String, int>();// Available resources after first allocation Dictionary<String, int> availsum = new Dictionary<string, int>(); //Start while (true) { Console.WriteLine(" What is number of resources to be shared? : "); if (!int.TryParse(Console.ReadLine(), out n)) { Console.WriteLine(" Error Please provide valid number --- {0}!", n); } else { break; } } //get the maximum number of each Resources Ie Total Resources Available while (true && n>0) { Console.WriteLine("Using a comma delimited list(eg 0, 0, 0, 0) list maximum of each of the {0} resources : ", n); String temp; temp = Console.ReadLine(); if (!String.IsNullOrEmpty(temp)) { String[] maxR = temp.Split(','); for (int a = 1; a <= n; a++) { MaxR.Add("Resource#" + a.ToString(), Convert.ToInt32(maxR[a])); } break; } } while (true && n>0) { Console.Write("Enter total number of processes to share the available resources :"); if (!int.TryParse(Console.Read().ToString(), out proc_num)) { Console.WriteLine(" Error Please provide valid number --- {0}!", proc_num); } else { break; } } if(proc_num > 0) { //Request Process Max and allocated resources data for (int i = 1; i <= proc_num; i++) { Console.Write("Using a comma delimited list, Enter total number of Resources 1 through {0} are needed by PROCESS#{1} ?", n, i); String[] temps = Console.ReadLine().Split(','); SysProcess tempproc = new SysProcess("Process#" + i.ToString()); for (int a = 0; a < temps.Length; a++) { tempproc.Add_max_resource("Resource#" + (a + 1).ToString(), Convert.ToInt32(temps[a])); } //How many resources have already been allocated to each resource temps = null; Console.Write("Using a comma delimited list,Enter number of resources 1 through {0} already allocated to PROCESS#{1} ? ", n, i); temps = Console.ReadLine().Split(','); for (int a = 0; a < temps.Length; a++) { tempproc.add_alloc_resource("Resource#" + (a + 1).ToString(), Convert.ToInt32(temps[a])); } processes.Add("Process#" + i.ToString(), tempproc); } Console.WriteLine("Processing . . . "); Console.WriteLine(); Console.WriteLine("Available resources "); //Compute Available Resources for (int i = 0; i < n; i++) { if (!availsum.ContainsKey("Resource#" + (i + 1).ToString())) availsum.Add("Resource#" + (i + 1).ToString(), 0); foreach (SysProcess sp in processes.Values) { //add sum up the available availsum["Resource#" + (i + 1).ToString()] += sp.alloc_resources["Resource#" + (i + 1).ToString()]; } } //print out the availables we computed Console.Write(" avail< "); for (int j = 0; j < n; j++) { Console.Write(availsum["Resource#" + (j + 1).ToString()] + ","); if (j + 1 == n)//if this is the last one, go ahead and output the rest Console.Write("{0} > ", availsum["Resource#" + (j + 1).ToString()]); } // Printing resources still needed Console.WriteLine(); foreach (SysProcess p in processes.Values) { p.print_needed(); } //a) Find a row in the Need matrix which is less than the Available vector. //If such a row exists, then the process represented by that row may complete //with those additional resources. If no such row exists, eventual deadlock is possible. Dictionary<String, int> _currentavailsum; foreach (SysProcess p in processes.Values) { int TotalSproccounter = 0; String safelead; if (isprocessSafe(n, p, availsum)) { TotalSproccounter++; safelead = p.id; _currentavailsum = new Dictionary<String, int>(); _currentavailsum = availsum;//get a copy of the original data to begin with foreach (SysProcess q in processes.Values) { if (q != p)//we only want to compare with the others from here { if (isprocessSafe(n, p, _currentavailsum)) { update_availsum(n, q, ref _currentavailsum);//update the currentavail count TotalSproccounter++; //update print safelead += ", " + q.id; } } } if (TotalSproccounter == proc_num) { Console.WriteLine("Safe allocation < {0} >", safelead); } else { Console.WriteLine("Deadlock reached/unsafe allocation : < {0} >", safelead); } } } } Console.ReadLine(); } //compares the number of resources needed against the number of resources available public static Boolean isprocessSafe(int n, SysProcess p, IDictionary<String, int> avail) { int safecount = 0; foreach (String resourcekey in avail.Keys) { if (p.need_resources.ContainsKey(resourcekey) && p.need_resources[resourcekey] <= avail[resourcekey]) { safecount++; } } if (safecount == n) { return true; } return false; } //compares the number of resources needed against the number of resources available public static void update_availsum(int n, SysProcess p, ref Dictionary<String, int> _currentavailsum) { foreach (String resourcekey in _currentavailsum.Keys) { if (p.need_resources.ContainsKey(resourcekey)) { _currentavailsum[resourcekey] += p.need_resources[resourcekey]; } } } } //container class for processes public class SysProcess { public String id { get; set; } Dictionary<String, int> _max_resources = null; // will hold the Resource name and the the number of resources Dictionary<String, int> _alloc_resources = null;//allocated resources Dictionary<String, int> _need_resources = null;//allocated resources public Dictionary<String, int> max_resources { get { return _max_resources; } } public Dictionary<String, int> alloc_resources { get { return _alloc_resources; } } public Dictionary<String, int> need_resources { get { return _need_resources; } } public SysProcess(String procID) { _max_resources = new Dictionary<String, int>(); _alloc_resources = new Dictionary<String, int>(); id = procID; } public void Add_max_resource(String resource, int count) { _max_resources.Add(resource, count); } public void add_alloc_resource(String resource, int count) { _alloc_resources.Add(resource, count); _need_resources.Add(resource, _max_resources[resource] - alloc_resources[resource]); } public void print_needed() { Console.Write(id); foreach (int s in _need_resources.Values) { Console.Write(" {0}", s); } } } 

在这里添加整个代码可能是一个好主意，因为我仍然无法找出这个问题。 请帮忙

  static void Main(string[] args) { string value = Console.Read().ToString(); Console.WriteLine("You entered: {0}", value); Console.WriteLine("Press ENTER to continue..."); Console.ReadLine(); // Returns immediately. Console.WriteLine("Continuing...."); } 

  string value = Console.ReadLine(); 

 private void clearInputBuffer() { while(Console.KeyAvailable) { Console.Read(); // read next key, but discard } }
