Assembly:  mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public ReadOnly Property IsSpecialName As Boolean

public bool IsSpecialName { get; }

Property Value

Type: System.Boolean
true if the field has the FieldAttributes.SpecialName attribute set; otherwise, false.

Exceptions

Exception Condition
MethodAccessException

Remarks

Names that begin with or contain an underscore character (_), property accessors, and operator overloading methods are examples of names that might require special treatment by some compilers.

Examples

The following example shows whether or not the fields in the class have the FieldAttributes.SpecialName attribute.

NoteNote:

To run this example, see Building Examples That Use a Demo Method and a TextBlock Control.

 
Imports System.Reflection

Class Example

    Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)

        Dim myType As Type = GetType(EventAttributes)

        outputBlock.Text = _
            String.Format("Fields of {0}, flagging FieldAttributes.SpecialName:" & vbLf, _
                          myType.Name)

        For Each fi As FieldInfo in myType.GetFields()
            ' Determine whether or not each field has a special name.
            If fi.IsSpecialName Then
                outputBlock.Text &= _
                    String.Format("{0} has the FieldAttributes.SpecialName attribute." & vbLf, _
                                  fi.Name)
            Else
                outputBlock.Text &= fi.Name & vbLf
            End If
        Next fi

    End Sub
