RaisePropertyChanged - 而從C＃代碼轉換到VB.NET

Question

錯誤我想下面這段C＃代碼轉換爲VB.NET

/// <summary> 
/// Attempts to raise the PropertyChanged event, and invokes the virtual AfterPropertyChanged 
/// method, regardless of whether the event was raised or not. 
/// </summary> 
/// <param name="propertyName"> 
/// The property which was changed. 
/// </param> 

    protected void RaisePropertyChanged(string propertyName) 
    { 
     this.VerifyProperty(propertyName); 

     PropertyChangedEventHandler handler = this.PropertyChanged; 
     if (handler != null) 
     { 
      //Get the cached event args. 
      PropertyChangedEventArgs args = GetPropertyChangedEventArgs(propertyName); 

      //Raise the PropertyChanged event. 
      handler(this, args); 
     } 
    } 

轉換後，VB代碼是：

''' <summary> 
''' Attempts to raise the PropertyChanged event, and invokes the virtual AfterPropertyChanged 
''' method, regardless of whether the event was raised or not. 
''' </summary> 
''' <param name="propertyName"> 
''' The property which was changed. 
''' </param> 
Protected Sub RaisePropertyChanged(propertyName As String) 
    Me.VerifyProperty(propertyName) 

    Dim handler As PropertyChangedEventHandler = Me.PropertyChanged 

    If handler IsNot Nothing Then 
     'Get the cached event args. 
     Dim args As PropertyChangedEventArgs = GetPropertyChangedEventArgs(propertyName) 

     'Raise the PropertyChanged event. 
     handler.Invoke(Me, args) 
    End If 
End Sub 

我使用了Telerik Code Converter，它不能完全轉換事件和XML屬性等。

問題是，Visual Studio顯示以下錯誤： 錯誤103'公共事件PropertyChanged（sender As Object，e As System.ComponentModel.PropertyChangedEventArgs）'是一個事件，無法直接調用。使用'RaiseEvent'語句來引發一個事件。

你能好心幫我這個，因爲我不擅長VB.NET語法和這樣的:(

Answer 1

只需更換 昏暗處理程序作爲PropertyChangedEventHandler = Me.PropertyChanged 與 昏暗處理程序作爲PropertyChangedEventHandler = Me.PropertyChangedEvent

Answer 2

您需要先定義的PropertyChanged可變

這樣的： 公共事件PropertyChangedEventHandler的PropertyChanged;
