Examples

This example demonstrates using a CodeConditionStatement to represent an if statement with an else block.

// Create a CodeConditionStatement that tests a boolean value named boolean.
array<CodeStatement^>^temp0 = {gcnew CodeCommentStatement( "If condition is true, execute these statements." )};
array<CodeStatement^>^temp1 = {gcnew CodeCommentStatement( "Else block. If condition is false, execute these statements." )};

// The statements to execute if the condition evalues to false.
CodeConditionStatement^ conditionalStatement = gcnew CodeConditionStatement( gcnew CodeVariableReferenceExpression( "boolean" ),temp0,temp1 );

// A C# code generator produces the following source code for the preceeding example code:
// if (boolean) 
// {
//     // If condition is true, execute these statements.
// }
// else {
//     // Else block. If condition is false, execute these statements.
// }

// Create a CodeConditionStatement that tests a boolean value named boolean.
CodeConditionStatement conditionalStatement = new CodeConditionStatement(
    // The condition to test.
    new CodeVariableReferenceExpression("boolean"),
    // The statements to execute if the condition evaluates to true.
    new CodeStatement[] { new CodeCommentStatement("If condition is true, execute these statements.") },
    // The statements to execute if the condition evalues to false.
    new CodeStatement[] { new CodeCommentStatement("Else block. If condition is false, execute these statements.") } );

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

// if (boolean)
// {
    //     // If condition is true, execute these statements.
// }
// else {
//     // Else block. If condition is false, execute these statements.
    // }

' Create a CodeConditionStatement that tests a boolean value named boolean.
 Dim conditionalStatement As New CodeConditionStatement( _
      New CodeVariableReferenceExpression("boolean"), _
      New CodeStatement() {New CodeCommentStatement("If condition is true, execute these statements.")}, _
      New CodeStatement() {New CodeCommentStatement("Else block. If condition is false, execute these statements.")})

' A Visual Basic code generator produces the following source code for the preceeding example code:

' If [boolean] Then
'     'If condition is true, execute these statements.
' Else
'     'Else block. If condition is false, execute these statements.

Remarks

CodeConditionStatement can be used to represent code that consists of a conditional expression, a collection of statements to execute if the conditional expression evaluates to true, and an optional collection of statements to execute if the conditional expression evaluates to false. A CodeConditionStatement is generated in many languages as an if statement.

The Condition property indicates the expression to test. The TrueStatements property contains the statements to execute if the expression to test evaluates to true. The FalseStatements property contains the statements to execute if the expression to test evaluates to false.

Constructors

CodeConditionStatement()	Initializes a new instance of the CodeConditionStatement class.
CodeConditionStatement(CodeExpression, CodeStatement[], CodeStatement[])	Initializes a new instance of the CodeConditionStatement class using the specified condition and statements.
CodeConditionStatement(CodeExpression, CodeStatement[])	Initializes a new instance of the CodeConditionStatement class using the specified condition and statements.

Properties

Condition	Gets or sets the expression to evaluate true or false.
EndDirectives	Gets a CodeDirectiveCollection object that contains end directives. (Inherited from CodeStatement)
FalseStatements	Gets the collection of statements to execute if the conditional expression evaluates to false.
LinePragma	Gets or sets the line on which the code statement occurs. (Inherited from CodeStatement)
StartDirectives	Gets a CodeDirectiveCollection object that contains start directives. (Inherited from CodeStatement)
TrueStatements	Gets the collection of statements to execute if the conditional expression evaluates to true.
UserData	Gets the user-definable data for the current object. (Inherited from CodeObject)

Methods

Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)
