DebuggerBrowsableAttribute(DebuggerBrowsableState) 构造函数

定义

命名空间:

System.Diagnostics

程序集:

System.Runtime.dll

Source:

DebuggerBrowsableAttribute.cs

初始化 DebuggerBrowsableAttribute 类的新实例。

public:
 DebuggerBrowsableAttribute(System::Diagnostics::DebuggerBrowsableState state);

public DebuggerBrowsableAttribute (System.Diagnostics.DebuggerBrowsableState state);

new System.Diagnostics.DebuggerBrowsableAttribute : System.Diagnostics.DebuggerBrowsableState -> System.Diagnostics.DebuggerBrowsableAttribute

Public Sub New (state As DebuggerBrowsableState)

参数

state

DebuggerBrowsableState

DebuggerBrowsableState 值之一，指定成员的显示方式。

例外

ArgumentOutOfRangeException

state 不是 DebuggerBrowsableState 值之一。

示例

下面的代码示例演示如何使用 DebuggerBrowsableAttribute 特性指示调试器不显示属性的根 (属性名称) Keys ，而是显示获取的数组 Keys 的元素。 此代码示例是为 DebuggerDisplayAttribute 类提供的一个更大示例的一部分。

[DebuggerBrowsable(DebuggerBrowsableState::RootHidden)]
property array<KeyValuePairs^>^ Keys
{
    array<KeyValuePairs^>^ get()
    {
        array<KeyValuePairs^>^ keys = gcnew array<KeyValuePairs^>(hashtable->Count);

        IEnumerator^ ie = hashtable->Keys->GetEnumerator();
        int i = 0;
        Object^ key;
        while (ie->MoveNext())
        {
            key = ie->Current;
            keys[i] = gcnew KeyValuePairs(hashtable, key, hashtable[key]);
            i++;
        }
        return keys;
    }
}

[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;
    }
}

<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

注解

此属性只能应用于属性和字段。
