Esempio

In questo esempio viene illustrato l'uso di per CodeConditionStatement rappresentare un'istruzione if con un else blocco.

// 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.

Commenti

CodeConditionStatement può essere usato per rappresentare il codice costituito da un'espressione condizionale, una raccolta di istruzioni da eseguire se l'espressione condizionale restituisce truee una raccolta facoltativa di istruzioni da eseguire se l'espressione condizionale restituisce false. Un CodeConditionStatement oggetto viene generato in molte lingue come istruzione if .

La Condition proprietà indica l'espressione da testare. La TrueStatements proprietà contiene le istruzioni da eseguire se l'espressione da testare restituisce true. La FalseStatements proprietà contiene le istruzioni da eseguire se l'espressione da testare restituisce false.
