public bool Contains (System.CodeDom.CodeTypeDeclaration value);
member this.Contains : System.CodeDom.CodeTypeDeclaration -> bool
Public Function Contains (value As CodeTypeDeclaration) As Boolean
参数
- value
- CodeTypeDeclaration
要在此集合中搜索的 CodeTypeDeclaration 对象。

示例
以下示例演示如何使用 Contains 方法在 中CodeTypeDeclarationCollection查找 CodeTypeDeclaration 对象。
// Tests for the presence of a CodeTypeDeclaration in the
// collection, and retrieves its index if it is found.
CodeTypeDeclaration^ testDeclaration = gcnew CodeTypeDeclaration( "TestType" );
int itemIndex = -1;
if ( collection->Contains( testDeclaration ) )
itemIndex = collection->IndexOf( testDeclaration );
// Tests for the presence of a CodeTypeDeclaration in the
// collection, and retrieves its index if it is found.
CodeTypeDeclaration testDeclaration = new CodeTypeDeclaration("TestType");
int itemIndex = -1;
if( collection.Contains( testDeclaration ) )
itemIndex = collection.IndexOf( testDeclaration );
' Tests for the presence of a CodeTypeDeclaration in the
' collection, and retrieves its index if it is found.
Dim testDeclaration As New CodeTypeDeclaration("TestType")
Dim itemIndex As Integer = -1
If collection.Contains(testDeclaration) Then
itemIndex = collection.IndexOf(testDeclaration)
End If
