PropertyInfo.GetGetMethod Method (Boolean)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

When overridden in a derived class, returns the public or non-public get accessor for this property.

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

Syntax

'Declaration
Public MustOverride Function GetGetMethod ( _
    nonPublic As Boolean _
) As MethodInfo

public abstract MethodInfo GetGetMethod(
    bool nonPublic
)

Parameters

nonPublic
Type: System.Boolean
true to return a non-public accessor; otherwise, false.

Return Value

Type: System.Reflection.MethodInfo
The get accessor for this property, if nonPublic is true. Returns nulla null reference (Nothing in Visual Basic) if nonPublic is false and the get accessor is non-public, or if nonPublic is true but no get accessor exists.

Exceptions

Exception	Condition
MethodAccessException	Application code attempts to access this member late-bound, for example by using the Type.InvokeMember method.

Remarks

This property is the MethodInfo representing the get accessor.

To use the GetGetMethod method, first get the class Type. From the Type, get the PropertyInfo. From the PropertyInfo, use the GetGetMethod method.

Examples

The following example demonstrates both overloads of the GetGetMethod method. The example defines a public property and a protected property. The example uses the GetGetMethod() and GetGetMethod(Boolean) method overloads to display the get accessors of both properties. In the first case, only the get accessor for the public property is displayed.

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

Class Example

   ' Define properties with different access levels.

   Private myCaption As String = "A Default caption"
   Public ReadOnly Property Caption() As String
      Get
         Return myCaption
      End Get
   End Property

   Private myText As String = "Default text."
   Protected ReadOnly Property Text() As String
      Get
         Return myText
      End Get
   End Property


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

      ' Get the PropertyInfo objects.
      Dim captionInfo As PropertyInfo = GetType(Example).GetProperty("Caption")
      Dim textInfo As PropertyInfo = _
         GetType(Example).GetProperty("Text", _
                                      BindingFlags.NonPublic Or BindingFlags.Instance)

      outputBlock.Text &= "Public get accessors:" & vbLf

      ' List the public get accessors.
      Dim publicGetAccessors() As MethodInfo = { captionInfo.GetGetMethod(), _
                                                 textInfo.GetGetMethod() }

      For Each mi As MethodInfo In publicGetAccessors
         If mi Is Nothing Then
