CodeVariableDeclarationStatement Class

Represents a variable declaration.

Namespace:  System.CodeDom
Assembly:  System (in System.dll)

public class CodeVariableDeclarationStatement : CodeStatement

CodeVariableDeclarationStatement can be used to represent code that declares a variable.

The Type property specifies the type of the variable to declare. The Name property specifies the name of the variable to declare. The InitExpression property is optional, and specifies an initialization expression to assign to the variable after it is created.


Some languages can implement the optional variable initialization expression by making a separate assignment statement after the variable declaration.

This example demonstrates using a CodeVariableDeclarationStatement to declare a variable.

CodeVariableDeclarationStatement variableDeclaration = new CodeVariableDeclarationStatement(
    // Type of the variable to declare. 
    // Name of the variable to declare. 
    // Optional initExpression parameter initializes the variable. 
    new CodePrimitiveExpression("Testing") );

// A C# code generator produces the following source code for the preceeding example code: 

// string TestString = "Testing";
