DebuggerTypeProxyAttribute Constructors

Definition

Namespace:

System.Diagnostics

Assemblies:

netstandard.dll, System.Runtime.dll

Initializes a new instance of the DebuggerTypeProxyAttribute class using the type of the proxy.

Overloads

DebuggerTypeProxyAttribute(String)	Initializes a new instance of the DebuggerTypeProxyAttribute class using the type name of the proxy.
DebuggerTypeProxyAttribute(Type)	Initializes a new instance of the DebuggerTypeProxyAttribute class using the type of the proxy.

DebuggerTypeProxyAttribute(String)

Source:

DebuggerTypeProxyAttribute.cs

Initializes a new instance of the DebuggerTypeProxyAttribute class using the type name of the proxy.

C#

public DebuggerTypeProxyAttribute(string typeName);

Parameters

typeName

String

The type name of the proxy type.

Remarks

The debugger creates a new instance of the type proxy class every time it needs to display a variable of the target type. This can have performance implications. As a result, you should not do any more work in the constructor than absolutely necessary.

DebuggerTypeProxyAttribute(Type)

Source:

DebuggerTypeProxyAttribute.cs

Initializes a new instance of the DebuggerTypeProxyAttribute class using the type of the proxy.

C#

public DebuggerTypeProxyAttribute(Type type);

Parameters

type

Type

The proxy type.

Exceptions

ArgumentNullException

type is null.

Examples

The following code example shows the use of the DebuggerTypeProxyAttribute(Type) constructor to specify a debugger display proxy. This code example is part of a larger example provided for the DebuggerDisplayAttribute class.

C#

[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;
            }
        }
    }
}
