我正在将一些代码从VB.NET迁移到C#(3.5).
我找到了以下结构：
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对象,如下所示：
Button1.Click += Button1_Click;
protected void Button1_Click(object sender,EventArgs e)
{
//do something.
}
但是C#确实具有这样做的简洁能力：
Button1.Click += (sender,e)=>
{
//do something
}
