error cannot override Public Overrides Property because they differ by their return in vb.net

Hi kana250688,

A Property statement specifies Overrides when no type with the same name exists in a base class.

1. To correct this error, check that the type name is spelled correctly.

2. Remove the Overrides keyword.

Private minimumSize_Conflict? As Size = Nothing
Private maximumSize_Conflict? As Size = Nothing
Private minimumClientSize_Conflict As Size
Private maximumClientSize_Conflict As Size

Public Property MinimumSize As Size
    Get
        If minimumSize_Conflict.HasValue Then
            Return minimumSize_Conflict.Value
        End If
        Return MyBase.MinimumSize
    End Get
    Set(value As Size)
        minimumSize_Conflict = value
        If IsInitializing Then
            Return
        End If
        Dim maxSize As Size = MaximumSize
        MyBase.MinimumSize = value
        If maxSize <> MaximumSize Then
            maximumClientSize_Conflict = ClientSizeFromSize(MaximumSize)
        End If
    End Set
End Property

Public Property MaximumSize As Size
    Get
        If maximumSize_Conflict.HasValue Then
            Return maximumSize_Conflict.Value
        End If
        Return MyBase.MaximumSize
    End Get
    Set(value As Size)
        maximumSize_Conflict = value
        If IsInitializing Then
            Return
        End If
        Dim minSize As Size = MinimumSize
        MyBase.MaximumSize = value
        If MinimumSize <> minSize Then
            minimumClientSize_Conflict = ClientSizeFromSize(MinimumSize)
        End If
    End Set
End Property

Protected Function SizeFromClientSize(clientSize As Size) As Size
    clientSize.Width += ClientMargin.Horizontal
    clientSize.Height += ClientMargin.Vertical

    Return clientSize
End Function

Dear Sir,

 Thanks for replyy. Sorry I'm Late.

After I follow your answer but there is an error, please guide me from you

Below Code in vb.net

'Public Overrides Property MinimumSize As SIZE


Public Property MinimumSize As SIZE
	Get
		If minimumSize_Conflict.HasValue Then
			Return minimumSize_Conflict.Value
		End If
'error below line Value of type 'Size' cannot be converted to 'SIZE'.`
		Return MyBase.MinimumSize
	End Get
	Set(ByVal value As SIZE)
		minimumSize_Conflict = value
		If IsInitializing Then
			Return
		End If
		Dim maxSize As SIZE = MaximumSize
		MyBase.MinimumSize = value
`error below line Operator '<>' is not defined for types 'SIZE' and 'SIZE'.
		If maxSize <> MaximumSize Then
			MaximumClientSize = ClientSizeFromSize(MaximumSize)
		End If
	End Set
End Property
'Public Overrides Property MaximumSize As SIZE
Public Property MaximumSize As SIZE
	Get
		If maximumSize_Conflict.HasValue Then
			Return maximumSize_Conflict.Value
		End If
'error below line Value of type 'Size' cannot be converted to 'SIZE'.`
		Return MyBase.MaximumSize
	End Get
	Set(ByVal value As SIZE)
		maximumSize_Conflict = value
		If IsInitializing Then
			Return
		End If
		Dim minSize As SIZE = MinimumSize
		MyBase.MaximumSize = value
`error below line Operator '<>' is not defined for types 'SIZE' and 'SIZE'.
		If MinimumSize <> minSize Then
			MinimumClientSize = ClientSizeFromSize(MinimumSize)
		End If
	End Set
End Property

error : ''Height' is not a member of 'SIZE'. & 'Width' is not a member of 'SIZE'.

Protected Function ConstrainMinimumClientSize(ByVal value As Size) As Size
			value.Width = Math.Max(0, value.Width)
			value.Height = Math.Max(0, value.Height)
			Return value
End Function

I have verified the code witch you have shared.

There is no issue in the code.

Its difficult to reproduce the error at our end.

Will you please let us know, at which scenario and which case you are getting the error?

Also let us know where you have implemented the code?
