解説

CodeMethodReturnStatement を使用して、値を返す return ステートメントを表すことができます。Expression プロパティは、返す値を指定します。

使用例

CodeMethodReturnStatement を使用して、メソッドから値を返す例を次に示します。

Visual Basic

' Defines a method that returns a string passed to it.
Dim method1 As New CodeMemberMethod()
method1.Name = "ReturnString"
method1.ReturnType = New CodeTypeReference("System.String")
method1.Parameters.Add(New CodeParameterDeclarationExpression("System.String",
 "text"))
method1.Statements.Add(New CodeMethodReturnStatement(New
 CodeArgumentReferenceExpression("text")))

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

'   Private Function ReturnString(ByVal [text] As String) As String
'       Return [Text]
'   End Function

// Defines a method that returns a string passed to it.
CodeMemberMethod method1 = new CodeMemberMethod();           
 
method1.Name = "ReturnString";
method1.ReturnType = new CodeTypeReference("System.String");
method1.Parameters.Add( new CodeParameterDeclarationExpression("System.String",
 "text") );
method1.Statements.Add( new CodeMethodReturnStatement( new
 CodeArgumentReferenceExpression("text") ) );            

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

//    private string ReturnString(string text) 
//    {
//        return text;
//    }

C++

// Defines a method that returns a string passed to it.
CodeMemberMethod^ method1 = gcnew CodeMemberMethod;
method1->Name = "ReturnString";
method1->ReturnType = gcnew CodeTypeReference( "System.String" );
method1->Parameters->Add( gcnew CodeParameterDeclarationExpression( "System.String","text"
 ) );
method1->Statements->Add( gcnew CodeMethodReturnStatement( gcnew CodeArgumentReferenceExpression(
 "text" ) ) );

// A C# code generator produces the following source code for the preceeding
 example code:
//    private string ReturnString(string text) 
//    {
//        return text;
//    }

// Defines a method that returns a string passed to it.
CodeMemberMethod method1 = new CodeMemberMethod();
method1.set_Name("ReturnString");
method1.set_ReturnType(new CodeTypeReference("System.String"));
method1.get_Parameters().Add(new CodeParameterDeclarationExpression(
    "System.String", "text"));
method1.get_Statements().Add(new CodeMethodReturnStatement(new
 
    CodeArgumentReferenceExpression("text")));
// A VJ# code generator produces the following source code for 
// the preceeding example code:
//    private String ReturnString(String text) 
//    {
//        return text;
//    } //ReturnString
