範例

下列範例會Contains使用 方法來搜尋 中CodeAttributeArgumentCollection是否有特定CodeAttributeArgument物件，並取得找到它的索引值。

// Tests for the presence of a CodeAttributeArgument 
// within the collection, and retrieves its index if it is found.
CodeAttributeArgument^ testArgument = gcnew CodeAttributeArgument( "Test Boolean Argument",gcnew CodePrimitiveExpression( true ) );
int itemIndex = -1;
if ( collection->Contains( testArgument ) )
   itemIndex = collection->IndexOf( testArgument );

// Tests for the presence of a CodeAttributeArgument
// within the collection, and retrieves its index if it is found.
CodeAttributeArgument testArgument = new CodeAttributeArgument("Test Boolean Argument", new CodePrimitiveExpression(true));
int itemIndex = -1;
if( collection.Contains( testArgument ) )
    itemIndex = collection.IndexOf( testArgument );

' Tests for the presence of a CodeAttributeArgument in 
' the collection, and retrieves its index if it is found.
Dim testArgument As New CodeAttributeArgument("Test Boolean Argument", New CodePrimitiveExpression(True))
Dim itemIndex As Integer = -1
If collection.Contains(testArgument) Then
    itemIndex = collection.IndexOf(testArgument)
End If
