c# - 将方法传递给 C# 中具有多个参数的 Thread

Question

我想在线程中执行一个方法。该方法有多个参数并期望返回值。任何人都可以帮忙吗？

Answer 1

Thread thread = new Thread(() => 
       {
          var result = YourMethod(param1, param2);
          // process result here (does not invoked on your main thread)
       });

如果您需要将结果返回到主线程，请考虑改用 Task (C# 4)：

var task = new Task<ReturnValueType>(() => YourMethod(param1, param2));
task.Start();

// later you can get value by calling task.Result;

或者使用以前版本的 C#

Func<Param1Type, Param2Type, ReturnValueType> func = YourMethod;            
IAsyncResult ar = func.BeginInvoke(param1, param2, null, null);
ar.AsyncWaitHandle.WaitOne();
var result = func.EndInvoke(ar);

Answer 2

Func<string, int, bool> func = SomeMethod;
AsyncCallback callback = ar => { bool retValue = func.EndInvoke(ar); DoSomethingWithTheValue(retValue };
func.BeginInvoke("hello", 42, callback, null);


...

bool SomeMethod(string param1, int param2) { ... }
