c# - 将 'Handles' 从 VB.NET 迁移到 C#

Question

我正在将一些代码从 VB.NET 迁移到 C# (3.5)。

我发现结构如下:

Public Event DataLoaded(ByVal sender As Object, ByVal e As EventArgs)

Protected Sub Mag_Button_Load_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Mag_Button_Load.Click
[..]
        RaiseEvent DataLoaded(Me, EventArgs.Empty)
End Sub
[..]

'Other Class
Private Sub LoadData(ByVal sender As Object, ByVal e As System.EventArgs) Handles oData.DataLoaded
[..]
End Sub

将此类行为转换为 C# 的最直接方法是什么？

我建议使用 Telerik Code Converter作为开始。

C# 没有像 VB.NET 那样通过“Handles”关键字轻松自动附加事件处理程序。

//EventHandler declaration
public event EventHandler  DataLoaded;
protected void Mag_Button_Load_Click(object sender, EventArgs e)
{

    //Raise Event
    if (DataLoaded != null) {
        DataLoaded(this, EventArgs.Empty);
    }
}

此外，您需要将事件处理程序分配给这样的对象:

Button1.Click += Button1_Click;

protected void Button1_Click(object sender, EventArgs e)
{
  //do something.
}

然而，C# 确实也具有执行此操作的简洁能力:

Button1.Click += (sender, e)=>
{
    //do something
}
