将VB.NET转换为C＃接口

Question

我需要将VB.NET接口转换为C＃接口的帮助。 下面的代码定义一个Event，并在方法中引发它。

Public Event CampaignDetailSelected(ByVal listItem As ListItem) _
Implements ICampaignMaintenanceView.CampaignDetailSelected

...

RaiseEvent CampaignDetailSelected(DirectCast(lsbCampaignDetail.SelectedItem, ListItem))

它的接口是：

Public Interface ICampaignMaintenanceView
    Event CampaignDetailSelected(listItem As ListItem)
    ...
End Interface

当我通过转换器将接口推入上方时，它会转换事件，但还会包含一个委托，这在C＃中是不允许的。

谁能给我一个提示？

Answer 1

这是我在C＃和VB.NET上遇到的众多问题之一，尽管我很喜欢C＃，但VB.NET使事件变得更简单。

// Placed outside of the class
public delegate void CampaignDetailSelectedEventHandler(ListItem listItem);

// Test class to show to convert from vb.net to C# 
public class Test : ICampaignMaintenanceView
{
    public event CampaignDetailSelectedEventHandler CampaignDetailSelected; 


    protected virtual void OnCampaignDetailSelected(ListItem listItem)
    {
        if (CampaignDetailSelected != null)
        {
            CampaignDetailSelected(listItem);
        }
    }
}

您的C＃委托和接口应类似于：

public delegate void CampaignDetailSelectedEventHandler(ListItem listItem);

public interface ICampaignMaintenanceView
{
    event CampaignDetailSelectedEventHandler CampaignDetailSelected;
}
