示例

以下示例使用 Contains 方法搜索特定 CodeCatchClause 实例的存在，并获取找到该实例的索引值。

// Tests for the presence of a CodeCatchClause in the 
// collection, and retrieves its index if it is found.
CodeCatchClause^ testClause = gcnew CodeCatchClause( "e" );
int itemIndex = -1;
if ( collection->Contains( testClause ) )
   itemIndex = collection->IndexOf( testClause );

// Tests for the presence of a CodeCatchClause in the
// collection, and retrieves its index if it is found.
CodeCatchClause testClause = new CodeCatchClause("e");
int itemIndex = -1;
if( collection.Contains( testClause ) )
    itemIndex = collection.IndexOf( testClause );

' Tests for the presence of a CodeCatchClause in the 
' collection, and retrieves its index if it is found.
Dim testClause As New CodeCatchClause("e")
Dim itemIndex As Integer = -1
If collection.Contains(testClause) Then
    itemIndex = collection.IndexOf(testClause)
End If
