PropertyInfo.GetSetMethod Method (Boolean)

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

When overridden in a derived class, returns the set accessor for this property.

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

Syntax

Public MustOverride Function GetSetMethod ( _
    nonPublic As Boolean _
) As MethodInfo
public abstract MethodInfo GetSetMethod(
    bool nonPublic
)

Parameters

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

Return Value

Type: System.Reflection..::.MethodInfo

Value

Condition

The set accessor for this property.

The set accessor is public.

-or-

nonPublic is true and a set accessor exists.

nullNothingnullptra null reference (Nothing in Visual Basic)

nonPublic is false and the set accessor is non-public.

-or-

There is no set accessor because the property is read-only.

Exceptions

Exception Condition
MethodAccessException

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

Remarks

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

Examples

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

Class Example

   ' Define properties with different access levels.

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

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