範例

下列程式代碼範例示範如何使用 Contains 方法來判斷集合是否包含特定的 CodeDirective 物件。 這個範例是提供給 類別之較大範例的 CodeDirectiveCollection 一部分。

// Tests for the presence of a CodeDirective in the
// collection, and retrieves its index if it is found.
CodeDirective testDirective = new CodeRegionDirective(CodeRegionMode.Start, "Region1");
int itemIndex = -1;
if (collection.Contains(testDirective))
    itemIndex = collection.IndexOf(testDirective);

' Tests for the presence of a CodeDirective in the 
' collection, and retrieves its index if it is found.
Dim testDirective = New CodeRegionDirective(CodeRegionMode.Start, "Region1")
Dim itemIndex As Integer = -1
If collection.Contains(testDirective) Then
    itemIndex = collection.IndexOf(testDirective)
End If
