详解C#如何使用读写锁控制多线程写入

public class Program
{
    static int SuccessCount = 0;
    static int FailureCount = 0;
    static ReaderWriterLockSlim WriteLock = new ReaderWriterLockSlim();
 
    static void Main(string[] args)
    {
 
        Console.WriteLine("Hello, World!");
 
        Parallel.For(0, 30, action =>
        {
            WriteTest();
        });
 
        Console.WriteLine("写入中...");
        Console.ReadLine();
    }
 
    static void WriteTest()
    {
        try
        {
            WriteLock.EnterWriteLock();
            SuccessCount++;
            File.AppendAllText("test.txt", $"{Thread.CurrentThread.ManagedThreadId}, {DateTime.Now.ToString("yyyy-MM-dd:HH:mm:ss:ffff")},{SuccessCount},{Environment.NewLine}");
        }
        catch (Exception ex)
        {
            FailureCount++;
            Console.WriteLine($"Failure Count:{FailureCount}");
        }
        finally { WriteLock.ExitWriteLock(); }
    }
 
}
