Delegate w/ Lambda

Herrwolf1

What is the C# equivalent to the following VB.NET code?

Delegate Sub SetStatus(ByVal Text As String)

Private Sub SetStatusStrip(ByVal Text As String)
Dim d As New SetStatus(Sub()
' Do some work.
End Sub)
Me.Invoke(d, New Object() {Text})
End Sub

This seems homeworky but since you could just whip it through an autotranslater anyway, here you go:

delegate void SetStatus(string text);

private void SetStatusStrip(string text){
Invoke(text => {
// do some work
}, new object[] { text } );
}

I think that's right. Invoke is a bit sniffy sometimes, you might need to cast the lambda, but I don't think so. Although it seems like the VB method you're generating for the delegate doesn't actually use a parameter so there's no reason you need to use that delegate for the inner method.

Doesn't sound like homework to me; I don't know any schools that mix VB/C#, but I do know that managers "insist" on keeping their codebase in a single language :)

I assure you it's not homework. I've been programming (promoted from drafting) for about three years. I started in VB.Net and am now trying to convert to C#. That doesn't seem to work. How can I cast a lambda expression? Thanks for the auto translate idea. I ran the code through a couple and none seem to work. Thanks for your help.

internal delegate void SetStatus(string Text);

private void SetStatusStrip(string Text)
{
SetStatus d = new SetStatus(() => {
// Do some work.
});
this.Invoke(d, new object[] {Text});
}

Thank you sir. The following is what I ended up using and it works great.

SetStatus d = new SetStatus( (string myText) =>
{
// Do some work
});
this.Invoke(d, new object[] { _text });
