I'm not entirely sure what to call what C# does, so I haven't had any luck searching for the VB.Net equivalent syntax (if it exists, which I suspect it probably doesn't).
In c#, you can do this:
public void DoSomething() {
new MyHelper().DoIt(); // works just fine
}
But as far as I can tell, in VB.Net, you must assign the helper object to a local variable or you just get a syntax error:
Public Sub DoSomething()
New MyHelper().DoIt() ' won't compile
End Sub
Just one of those curiosity things I run into from day to day working on mixed language projects - often there is a开发者_开发百科 VB.Net equivalent which uses less than obvious syntax. Anyone?
The magic word here is Call.
Public Sub DoSomething()
Call (New MyHelper()).DoIt()
Call New MyHelper().DoIt()
End Sub
Gideon Engelberth is right about using Call. It is the best option.
Another option is to use a With statement:
With New MyHelper()
.DoIt()
End With
