示例

以下示例使用 Contains 该方法搜索特定 CodeParameterDeclarationExpression 对象是否存在并获取找到该对象的索引值。

// in the collection, and retrieves its index if it is found.
CodeParameterDeclarationExpression testParameter = new CodeParameterDeclarationExpression(typeof(int), "testIntArgument");
int itemIndex = -1;
if( collection.Contains( testParameter ) )
    itemIndex = collection.IndexOf( testParameter );

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