CodeAttributeArgumentCollection.IndexOf(CodeAttributeArgument) 方法
定义
获取指定的 CodeAttributeArgument 对象在集合中的索引(如果它已存在于该集合中)。Gets the index of the specified CodeAttributeArgument object in the collection, if it exists in the collection.
public:
int IndexOf(System::CodeDom::CodeAttributeArgument ^ value);
public int IndexOf (System.CodeDom.CodeAttributeArgument value);
member this.IndexOf : System.CodeDom.CodeAttributeArgument -> int
Public Function IndexOf (value As CodeAttributeArgument) As Integer
参数
- value
- CodeAttributeArgument
要在集合中定位的 CodeAttributeArgument 对象。The CodeAttributeArgument object to locate in the collection.
返回
如果在该集合中找到指定对象,则为此对象在该集合中的索引;否则为 -1。The index of the specified object, if found, in the collection; otherwise, -1.
示例
下面的示例搜索特定对象的状态 CodeAttributeArgument ,并使用 IndexOf 方法获取找到它的索引值。The following example searches for the presence of a specific CodeAttributeArgument object and uses the IndexOf method to get the index value at which it was found.
// 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
