将c＃转换为Vb获取错误消息，因为公共事件是一个事件，无法直接调用。使用'raiseevent'语句来引发事件 [英] Convert c# to Vb getting error message as public event is an event and cannot be called directly. use a 'raiseevent' statement to raise an event

问题描述

您好我将以下c＃代码转换为vb.net。

Hi i converted the following c# code to vb.net.

public Dropdown(CheckedComboBox ccbParent)
{
this.ccbParent = ccbParent;
InitializeComponent();
this.ShowInTaskbar = false;						
this.cclb.ItemCheck += new System.Windows.Forms.ItemCheckEventHandler(this.cclb_ItemCheck);
}

private void cclb_ItemCheck(object sender, ItemCheckEventArgs e)
{
if (ccbParent.ItemCheck != null)
{
ccbParent.ItemCheck(sender, e);
}
}

vb.net

vb.net

Public Sub New(ByVal ccbParent As PlexisCheckedComboBox)
	MyBase.New()
	Me.ccbParent = ccbParent
	InitializeComponent()
	Me.ShowInTaskbar = False
	AddHandler cclb.ItemCheck, AddressOf cclb_ItemCheck
End Sub
Private Sub cclb_ItemCheck(ByVal sender As Object, ByVal e As Windows.Forms.ItemCheckEventArgs)
If (Not (ccbParent.ItemCheck) Is Nothing) Then
ccbParent.ItemCheck(sender, e)
End If
End Sub

在转换的vb.net代码中我得到错误在以下行中作为

公共事件itemcheck（）是一个事件，不能直接调用。使用''raiseevent''语句来举起活动

In the converted vb.net code im getting error in the following line as
"public event itemcheck() is an event and cannot be called directly. use a ''raiseevent'' statement to raise an event"

If (Not (ccbParent.ItemCheck) Is Nothing) Then
ccbParent.ItemCheck(sender, e)

请帮忙解决问题

推荐答案

Public Sub New(ccbParent As CheckedComboBox)
    Me.ccbParent = ccbParent
    InitializeComponent()
    Me.ShowInTaskbar = False
    Me.cclb.ItemCheck += New System.Windows.Forms.ItemCheckEventHandler(AddressOf Me.cclb_ItemCheck)
End Sub

Private Sub cclb_ItemCheck(sender As Object, e As ItemCheckEventArgs)
    If ccbParent.ItemCheck IsNot Nothing Then
        ccbParent.ItemCheck(sender, e)
    End If
End Sub
