Quick FAQ: How to use “With…End With” VB statement in C#?

Q: With…End With VB (.NET) also statement is very handy time saver. It makes you able to initialize properties of the object within one statement. Is there equivalent for this “With…End With” statement in C#?

Dim myObj As New MyObj()
With myObj
    .OneProperty = "Hello"
    .AnotherProperty = 2008
    .YetOtherProperty = "World"
End With

A: Yes it is. You should use following syntax to archive the same functionality.

MyObj myObj = new MyObj {
                OneProperty = "Hello",
                AnotherProperty = 2008,
                YetOtherProperty = "World"
            };

By the way. VB.NET (with Linq extension) also has similar syntax

Dim myObj = New MyObj() {
    .OneProperty = "Hello"
    .AnotherProperty = 2008
    .YetOtherProperty = "World" }

In addition, it can be anonymous in both languages

VB.NET
Dim myObj = New With {
    .OneProperty = "Hello"
    .AnotherProperty = 2008
    .YetOtherProperty = "World" }

C#
var myObject = new {
                OneProperty = "Hello",
                AnotherProperty = 2008,
                YetOtherProperty = "World"
            };

Have a nice day.
