Question

The following code:

        CodeVariableDeclarationStatement variableDeclaration = new CodeVariableDeclarationStatement(
            // Type of the variable to declare.
            typeof(string),
            // Name of the variable to declare.
            "TestString");

Produces the following VB.Net Statement:

Dim TestString As String

What change would I need to make for it to look like this:

Dim TestString As New StringBuilder()

I’m interested in how to get that NEW keyword to appear.

Answer 1

Add a CodeObjectCreateExpression as a 3rd argument in the constructor:

CodeVariableDeclarationStatement variableDeclaration = new CodeVariableDeclarationStatement(
    // Type of the variable to declare.
    typeof(System.Text.StringBuilder),
    // Name of the variable to declare.
    "TestString",
    // A CodeExpression that indicates the initialization expression for the variable.
    new CodeObjectCreateExpression( typeof(System.Text.StringBuilder), new CodeExpression[] {} )
);
