DebuggerDisplayAttribute(String) Constructor

Definition

Namespace:

System.Diagnostics

Assembly:

System.Runtime.dll

Source:

DebuggerDisplayAttribute.cs

Initializes a new instance of the DebuggerDisplayAttribute class.

public:
 DebuggerDisplayAttribute(System::String ^ value);

public DebuggerDisplayAttribute (string? value);

new System.Diagnostics.DebuggerDisplayAttribute : string -> System.Diagnostics.DebuggerDisplayAttribute

Public Sub New (value As String)

Parameters

value

String

The string to be displayed in the value column for instances of the type; an empty string ("") causes the value column to be hidden.

Examples

The following code example causes the value of the Count property from the inherited Hashtable class to be displayed when the plus sign (+) is selected to expand the debugger display for an instance of MyHashtable. You must run the complete example, which is provided in the DebuggerDisplayAttribute class, to see the results.

[DebuggerDisplay("Count = {Count}")]
[DebuggerTypeProxy(HashtableDebugView::typeid)]
ref class MyHashtable : Hashtable

[DebuggerDisplay("Count = {Count}")]
[DebuggerTypeProxy(typeof(HashtableDebugView))]
class MyHashtable : Hashtable

<DebuggerDisplay("Count = {Count}"), DebuggerTypeProxy(GetType(MyHashtable.HashtableDebugView))> _
Class MyHashtable
    Inherits Hashtable

Remarks

The value parameter can contain braces ({ and }). The text within a pair of braces is evaluated as the name of a field, property, or method. For example, the following C# code causes "Count = 4" to be displayed when the plus sign (+) is selected to expand the debugger display for an instance of MyTable.

[DebuggerDisplay("Count = {count}")]  
class MyTable  
{  
    public int count = 4;  
}
