在C#中启动STAThread

Question

我仍然是C#的新手,尤其是C#中的线程.我正在尝试启动一个需要单线程单元的函数(STAThread)

但我无法编译以下代码:

该函数在一个名为的单独类中如下所示MyClass:

internal static string DoX(string n, string p)
        {
            // does some work here that requires STAThread
        }

我已经尝试了函数顶部的[STAThread]属性,但这不起作用.

所以我试图创建一个新的Thread如下:

 Thread t = new Thread(new ThreadStart(MyClass.DoX));

但这不会编译(最好的重载方法有无效的参数错误).然而,在线示例非常相似(这里的示例) 我做错了什么,我怎样才能简单地在新的STA线程中运行函数？

谢谢

Answer 1

Thread thread = new Thread(() => MyClass.DoX("abc", "def"));
thread.SetApartmentState(ApartmentState.STA);
thread.Start();

如果您需要该值,则可以将其"捕获"回变量,但请注意,该变量在其他线程结束之前不会具有该值:

int retVal = 0;
Thread thread = new Thread(() => {
    retVal = MyClass.DoX("abc", "def");
});
thread.SetApartmentState(ApartmentState.STA);
thread.Start();

或者更简单:

Thread thread = new Thread(() => {
    int retVal = MyClass.DoX("abc", "def");
    // do something with retVal
});
thread.SetApartmentState(ApartmentState.STA);
thread.Start();
