FieldInfo.MemberType Property
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Gets a value that indicates that this member is a field.
Namespace: System.Reflection
Assembly: mscorlib (in mscorlib.dll)
Syntax
Public Overrides ReadOnly Property MemberType As MemberTypes
public override MemberTypes MemberType { get; }
Property Value
Type: System.Reflection..::.MemberTypes
A value that indicates that this member is a field.
Exceptions
| Exception | Condition |
|---|---|
| MethodAccessException | This member is invoked late-bound through mechanisms such as Type..::.InvokeMember. |
Remarks
This property overrides MemberType. Therefore, when you examine a set of MemberInfo objects — for example, the array returned by GetMembers — the MemberType property returns MemberTypes..::.Field only when a given member is a field.
Examples
The following example determines whether each instance member of the Example class is a field and displays the result.
Note
To run this example, see Building examples that have static TextBlock controls for Windows Phone 8.
Imports System.Reflection
' Make a field.
Public Class Example
Private m_field As String = "a private field"
Public ReadOnly Property Field() As String
Get
Return m_field
End Get
End Property
Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
outputBlock.Text &= "Reflection.FieldInfo" & vbCrLf & vbCrLf
Dim instanceMembers() As MemberInfo = _
GetType(Example).GetMembers(BindingFlags.Public Or BindingFlags.NonPublic Or _
BindingFlags.Instance)
For Each mi As MemberInfo In instanceMembers
If mi.MemberType = MemberTypes.Field Then
outputBlock.Text += String.Format("{0} is a field. <----" & vbLf, mi.Name)
Else
outputBlock.Text += String.Format("{0} is not a field. " & vbLf, mi.Name)
End If
Next mi
End Sub
End Class
