开始在C＃中STAThread [英] Starting an STAThread in C#

问题描述

我仍然到C＃的一种新的，特别是在C＃中的线程。 我试图启动一个函数，需要一个单线程单元（ STAThread ）

但我不能够编译如下code：

该功能看起来在一个单独的类名为如下： MyClass的：

 内部静态字符串DOX（串N，串P）
        {
            //做了一些工作，在这里，需要STAThread
        }
 

我已经试过属性[STAThread]功能的顶部，但不起作用。

所以，我想创建一个新的主题如下：

 线程t =新主题（新的ThreadStart（MyClass.DoX））;
 

但这不会编译（最好重载的方法有无效的参数错误）。不过网上的例子非常相似（例如这里） 我在做什么错了，我怎么能简单地做出一个新的STA线程函数运行？

感谢

解决方案

 线程的线程=新主题（（）=＆GT; MyClass.DoX（ABC，高清）） ;
thread.SetApartmentState（ApartmentState.STA）;
thread.Start（）;
 

如果你需要的价值，你可以捕获的备份到一个变量，但请注意，该变量不会有值，直到另一个线程结束：

  INT retVal的= 0;
线程线程=新主题（（）=＆GT; {
    retVal的= MyClass.DoX（ABC，DEF）;
}）;
thread.SetApartmentState（ApartmentState.STA）;
thread.Start（）;
 

或者是简单的：

 线程的线程=新主题（（）=＆GT; {
    INT retVal的= MyClass.DoX（ABC，高清）;
    //做些什么retVal的
}）;
thread.SetApartmentState（ApartmentState.STA）;
thread.Start（）;
 

I am still kind of new to C#, and especially threading in C#. I am trying to start a function that requires a single threaded apartment (STAThread)

But I am not able to compile the following code:

The function looks as follows in a separate class called MyClass:

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

I have tried the attribute [STAThread] on top of the function but that does not work.

So I am trying to create a new Thread as follows:

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

but this will not compile (The best overloaded method has invalid arguments error). However the example online is very similar (example here) What am I doing wrong and how can I simply make a function run in a new STA thread?

Thanks

解决方案

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

If you need the value, you can "capture" that back into a variable, but note that the variable won't have the value until the end of the other thread:

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

or perhaps simpler:

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