Exemplos

Este exemplo demonstra como usar um CodeMethodInvokeExpression método para invocar um método.

CodeMethodInvokeExpression methodInvoke = new CodeMethodInvokeExpression(
    // targetObject that contains the method to invoke.
    new CodeThisReferenceExpression(),
    // methodName indicates the method to invoke.
    "Dispose",
    // parameters array contains the parameters for the method.
    new CodeExpression[] { new CodePrimitiveExpression(true) } );

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

// this.Dispose(true);

' This CodeMethodInvokeExpression calls Me.Dispose(true)

    ' The targetObject parameter indicates the object containing the method to invoke.
    ' The methodName parameter indicates the method to invoke.
    ' The parameters array contains the parameters for the method invoke.

    Dim methodInvoke As New CodeMethodInvokeExpression( _
       New CodeThisReferenceExpression(), _
       "Dispose", _
       New CodeExpression() {New CodePrimitiveExpression(True)})

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

    ' Me.Dispose(true)

Comentários

CodeMethodInvokeExpression pode ser usado para representar uma expressão que invoca um método.

A Method propriedade especifica o método a ser invocado. A Parameters propriedade indica os parâmetros a serem passados para o método. Use um CodeDirectionExpression para especificar a direção de campo de um parâmetro.
