定义

命名空间:

System.CodeDom

程序集:

System.CodeDom.dll

包:

System.CodeDom v8.0.0

Source:

CodeParameterDeclarationExpressionCollection.cs

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

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

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

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

Public Function Contains (value As CodeParameterDeclarationExpression) As Boolean

参数

value

CodeParameterDeclarationExpression

要在该集合中搜索的 CodeParameterDeclarationExpression。

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 方法搜索特定 CodeParameterDeclarationExpression 对象的存在，并获取找到该对象的索引值。

// Tests for the presence of a CodeParameterDeclarationExpression 
// in the collection, and retrieves its index if it is found.
CodeParameterDeclarationExpression^ testParameter = gcnew CodeParameterDeclarationExpression( int::typeid,"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.
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
