CodeAttributeDeclarationCollection.IndexOf(CodeAttributeDeclaration) 方法

定義

取得集合中指定之 CodeAttributeDeclaration 物件的索引 (如果它存在於集合中的話)。

public:
 int IndexOf(System::CodeDom::CodeAttributeDeclaration ^ value);
public int IndexOf (System.CodeDom.CodeAttributeDeclaration value);
member this.IndexOf : System.CodeDom.CodeAttributeDeclaration -> int
Public Function IndexOf (value As CodeAttributeDeclaration) As Integer

參數

value
CodeAttributeDeclaration

要放置在集合中的 CodeAttributeDeclaration 物件。

傳回

如果找到的話,索引位於指定物件的集合中,否則為 -1。

範例

下列範例會搜尋特定 CodeAttributeDeclaration 實例是否存在,並使用 IndexOf 方法來取得找到它的索引值。

// Tests for the presence of a CodeAttributeDeclaration in 
// the collection, and retrieves its index if it is found.
array<CodeAttributeArgument^>^temp3 = {gcnew CodeAttributeArgument( gcnew CodePrimitiveExpression( "Test Description" ) )};
CodeAttributeDeclaration^ testdeclaration = gcnew CodeAttributeDeclaration( "DescriptionAttribute",temp3 );
int itemIndex = -1;
if ( collection->Contains( testdeclaration ) )
   itemIndex = collection->IndexOf( testdeclaration );
// Tests for the presence of a CodeAttributeDeclaration in
// the collection, and retrieves its index if it is found.
CodeAttributeDeclaration testdeclaration = new CodeAttributeDeclaration("DescriptionAttribute", new CodeAttributeArgument(new CodePrimitiveExpression("Test Description")) );
int itemIndex = -1;
if( collection.Contains( testdeclaration ) )
    itemIndex = collection.IndexOf( testdeclaration );
' Tests for the presence of a CodeAttributeDeclaration in the 
' collection, and retrieves its index if it is found.
Dim testdeclaration As New CodeAttributeDeclaration("DescriptionAttribute", New CodeAttributeArgument(New CodePrimitiveExpression("Test Description")))
Dim itemIndex As Integer = -1
If collection.Contains(testdeclaration) Then
    itemIndex = collection.IndexOf(testdeclaration)
End If
