看看BeginInvoke的用法，亲爱的们

using System;
using System.Threading;
class MyTest
{
    delegate bool deleTest(string a,string b);
    static void Main(string[] args)
    {
        deleTest mytest = new deleTest(Test);
        IAsyncResult testRecult = mytest.BeginInvoke("a", "b", null, null);

        Write();
        
        Console.WriteLine(mytest.EndInvoke(testRecult));
    }
    public static bool Test(string s1, string s2)
    {
        Thread.Sleep(3000);
        Console.WriteLine("InTest");
        if (s1 == s2)
            return true;
        return false;
    }

    public static void Write()
    {
        Console.WriteLine("InWrite");
    }
}
/*
运行结果：

InWrite
InTest
False
*/
