使用代理的类型名称初始化类的新实例 DebuggerTypeProxyAttribute

public:
 DebuggerTypeProxyAttribute(System::String ^ typeName);
public DebuggerTypeProxyAttribute(string typeName);
new System.Diagnostics.DebuggerTypeProxyAttribute : string -> System.Diagnostics.DebuggerTypeProxyAttribute
Public Sub New (typeName As String)

参数

typeName
String

代理类型的类型名称。

注解

每次需要显示目标类型的变量时,调试器都会创建类型代理类的新实例。 这可能导致性能影响。 因此,不应在构造函数中执行任何比绝对必要的工作。

示例

下面的代码示例演示如何使用 DebuggerTypeProxyAttribute(Type) 构造函数指定调试器显示代理。 该代码示例是 DebuggerDisplayAttribute 类中的一个较大示例的一部分。

[DebuggerTypeProxy(typeof(HashtableDebugView))]
class MyHashtable : Hashtable
{
    private const string TestString = "This should not appear in the debug window.";

    internal class HashtableDebugView
    {
        private Hashtable hashtable;
        public const string TestString = "This should appear in the debug window.";
        public HashtableDebugView(Hashtable hashtable)
        {
            this.hashtable = hashtable;
        }

        [DebuggerBrowsable(DebuggerBrowsableState.RootHidden)]
        public KeyValuePairs[] Keys
        {
            get
            {
                KeyValuePairs[] keys = new KeyValuePairs[hashtable.Count];

                int i = 0;
                foreach(object key in hashtable.Keys)
                {
                    keys[i] = new KeyValuePairs(hashtable, key, hashtable[key]);
                    i++;
                }
                return keys;
            }
        }
    }
}
<DebuggerDisplay("Count = {Count}"), DebuggerTypeProxy(GetType(MyHashtable.HashtableDebugView))> _
Class MyHashtable
    Inherits Hashtable
    Private Const TestString As String = "This should not appear in the debug window."

    Friend Class HashtableDebugView
        Private hashtable As Hashtable
        Public Shared TestString As String = "This should appear in the debug window."

        Public Sub New(ByVal hashtable As Hashtable)
            Me.hashtable = hashtable
        End Sub

        <DebuggerBrowsable(DebuggerBrowsableState.RootHidden)> _
        ReadOnly Property Keys as KeyValuePairs()
            Get
                Dim nkeys(hashtable.Count) as KeyValuePairs

                Dim i as Integer = 0
                For Each key As Object In hashtable.Keys
                    nkeys(i) = New KeyValuePairs(hashtable, key, hashtable(key))
                    i = i + 1
                Next
                Return nkeys
            End Get
        End Property

    End Class
End Class
