DebuggerDisplayAttribute Constructor

Initializes a new instance of the DebuggerDisplayAttribute class.

Namespace:  System.Diagnostics
Assembly:  mscorlib (in mscorlib.dll)

public DebuggerDisplayAttribute(
	string value
)

Parameters

value
Type: System.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.

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.

[c#]

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

Attributes applied to properties referenced in the expression are not processed. For some compilers, a general expression may be allowed that has only implicit access to this reference for the current instance of the target type. The expression is limited; there is no access to aliases, locals, or pointers.

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

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