我只是将C#函数转换为VB.NET函数,但不知何故出现了一些错误。下面是我的C#函数。
public abstract class BaseFilterControl: UserControl,IFilterControl
{
public string PropertyName { get; set; }
public FilterDescriptorBase AssociatedDescriptor { get; set; }
public bool IsFirst { get; set; }
public abstract FilterDescriptorBase BuildDescriptor();
protected abstract void Initialize();
}
以下是我目前的VB功能
Public MustInherit Class BaseFilterControl
Inherits UserControl
Implements IFilterControl
Public Property PropertyName As String
Public Property AssociatedDescriptor As FilterDescriptorBase
Public Property IsFirst As Boolean
Public MustOverride Function BuildDescriptor() As FilterDescriptorBase
Protected MustOverride Sub Initialize()
End Class
我收到此错误:
BaseFilterControl must implement Function BuildDescriptor() As FilterDescriptorBase.
任何想法。请帮忙。谢谢
最佳答案
很好地实现接口方法的抽象方法。在VB中,您只需要指定该函数实现接口函数即可:
Public MustOverride Function BuildDescriptor() As FilterDescriptorBase Implements IFilterControl.BuildDescriptor
您可能需要为其他方法添加更多的“ Implements”子句-我对IFilterControl接口不熟悉。
