等待表单加载完成 [英] Wait until form is finished loading

问题描述

是否有某种布尔值可以用来检查表单实例是否已加载，或者等待表单加载?

Is there some sort of boolean that I can use to check whether the instance of a form is loaded, or otherwise wait until the form is loaded?

例如:

While(form_loaded == false) {
  Try {
    //do something
  }
  catch {
  }//do try catch so code won't barf
}

我不断收到以下异常:

System.InvalidOperationException"类型的第一次机会异常发生在 System.Windows.Forms.dll 中

A first chance exception of type 'System.InvalidOperationException' occurred in System.Windows.Forms.dll

System.Windows.Forms.dll 中发生类型为System.InvalidOperationException"的未处理异常

An unhandled exception of type 'System.InvalidOperationException' occurred in System.Windows.Forms.dll

附加信息:在创建窗口句柄之前，不能在控件上调用 Invoke 或 BeginInvoke.

Additional information: Invoke or BeginInvoke cannot be called on a control until the window handle has been created.

这就是我所担心的.

另外，如果需要更详细的解释，我可以尝试发布一些代码和/或更多输出调试信息.

Additionally if a more detailed explanation is needed I can try to post some code and/or some more output debugging information.

推荐答案

尝试像这样使用显示的事件

try to use the shown event something like this

 public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        this.Shown += new System.EventHandler(this.Form1_Shown);
    }

    private void Form1_Shown(object sender, EventArgs e)
    {

    }
}

希望能帮到你
