Exempel

I följande exempel används Contains metoden för att söka efter förekomsten av en specifik CodeAttributeDeclaration instans och hämtar indexvärdet där den hittades.

// Tests for the presence of a CodeAttributeDeclaration in
// the collection, and retrieves its index if it is found.
CodeAttributeDeclaration testdeclaration = new CodeAttributeDeclaration("DescriptionAttribute", new CodeAttributeArgument(new CodePrimitiveExpression("Test Description")) );
int itemIndex = -1;
if( collection.Contains( testdeclaration ) )
    itemIndex = collection.IndexOf( testdeclaration );

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