CodeAttributeArgumentCollection.Contains(CodeAttributeArgument) 方法

定义

命名空间:

System.CodeDom

程序集:

System.CodeDom.dll

包:

System.CodeDom v8.0.0

Source:

CodeAttributeArgumentCollection.cs

获取一个值，该值指示集合是否包含指定的 CodeAttributeArgument 对象。

public:
 bool Contains(System::CodeDom::CodeAttributeArgument ^ value);

public bool Contains (System.CodeDom.CodeAttributeArgument value);

member this.Contains : System.CodeDom.CodeAttributeArgument -> bool

Public Function Contains (value As CodeAttributeArgument) As Boolean

参数

value

CodeAttributeArgument

要在集合中定位的 CodeAttributeArgument 对象。

返回

Boolean

当集合包含指定的对象时为 true；否则为 false。

示例

以下示例使用 Contains 方法搜索 中CodeAttributeArgumentCollection是否存在特定CodeAttributeArgument对象，并获取找到该对象的索引值。

// 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
