Public methodCodeVariableDeclarationStatement(String, String)Initializes a new instance of the CodeVariableDeclarationStatement class using the specified data type name and variable name.
Public methodCodeVariableDeclarationStatement(Type, String)Initializes a new instance of the CodeVariableDeclarationStatement class using the specified data type and variable name.
Public methodCodeVariableDeclarationStatement(CodeTypeReference, String, CodeExpression)Initializes a new instance of the CodeVariableDeclarationStatement class using the specified data type, variable name, and initialization expression.
Public methodCodeVariableDeclarationStatement(String, String, CodeExpression)Initializes a new instance of the CodeVariableDeclarationStatement class using the specified data type, variable name, and initialization expression.

Public propertyInitExpressionGets or sets the initialization expression for the variable.
Public propertyLinePragmaGets or sets the line on which the code statement occurs. (Inherited from CodeStatement.)
Public propertyNameGets or sets the name of the variable.
Public propertyStartDirectivesGets a CodeDirectiveCollection object that contains start directives. (Inherited from CodeStatement.)
Public propertyTypeGets or sets the data type of the variable.
Public propertyUserDataGets the user-definable data for the current object. (Inherited from CodeObject.)

  NameDescription
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)

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.

NoteNote

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.

// Type of the variable to declare. 
// Name of the variable to declare. 
// Optional initExpression parameter initializes the variable.
CodeVariableDeclarationStatement^ variableDeclaration = gcnew CodeVariableDeclarationStatement( String::typeid,"TestString",gcnew CodePrimitiveExpression( "Testing" ) );

// A C# code generator produces the following source code for the preceeding example code: 
// string TestString = "Testing";
