推荐答案

东西，你必须做的：

重写主（）方法是这样的： Project + Properties, Application tab, change Output Type to "Windows Application" Project + Add Reference, select at least System.Windows.Forms and System.Drawing Locate your Main() method in the Program.cs source code file. Give it the [STAThread] attribute.

Rewrite the Main() method to look like this:

[STAThread]
static void Main() {
    Application.EnableVisualStyles();
    Application.SetCompatibleTextRenderingDefault(false);
    Application.Run(new YourMainForm());
}

更改YourMainForm到您的窗体类的名称。打捞现有的code在main（）方法是将可能是痛苦位。运行（）调用后，你不能离开它，该调用不会返回，直到用户关闭你的主要形式。

Change "YourMainForm" to the name of your form class. Salvaging your existing code in the Main() method is what will probably be the painful bit. You cannot leave it after the Run() call, that call won't return until the user closes your main form.
