问题描述

我将以下代码添加到我的 C# windows 窗体应用程序以在我单击关闭按钮时显示一个消息框.. 但它给了我以下错误..

I added following code to my C# windows form application to show a message box when i click the closing button.. But it gives me following error..

错误 CS0116 命名空间不能直接包含成员，例如字段或方法 ebay 源 C:\Users\Supun\Documents\Visual Studio2015\Projects\ebay source\ebay source\Form1.cs 107 Active

Error CS0116 A namespace cannot directly contain members such as fields or methods ebay source C:\Users\Supun\Documents\Visual Studio 2015\Projects\ebay source\ebay source\Form1.cs 107 Active

这是我使用的代码..

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
    DialogResult dialog = dialog = MessageBox.Show(
      "Do you really want to close the program?", 
      "SomeTitle", 
       MessageBoxButtons.YesNo);

    if (dialog == DialogResult.No)
    {
        e.Cancel = true;
    }
}

请问我需要做些什么来修复它?

What do I need to do to fix it please?

推荐答案

我想你已经在类之外声明了那个函数?

I would imagine you've declared that function outside of a class?

喜欢

namespace Something
{
    private void Method()
    {
    }
}

代替

namespace Something
{
    class MyClass
    {
        private void Method()
        {
        }
    }
}
