是/否消息框始终返回是-VB.Net [英] Yes/No message box always returns yes - VB.Net

问题描述

我正在尝试使用消息框，并尝试了一个简单的yes / no messagebox
，所以我编写了这段简单的代码。但是，无论我按什么按钮， chc变量始终返回1。我提供了代码，所以您可能会看到我做错了。

I was experimenting with message boxes, and tried a simple yes/no messagebox So I wrote this simple piece of code. However, the "chc" variable always returns as 1, no matter what button I press. I provided the code, so you maybe see what I did wrong. It is probably horribly wrong.

If MsgBoxResult.Yes Then
    chc = 1
ElseIf MsgBoxResult.No Then
    chc = 0
End If

MsgBox(chc)

推荐答案

MsgBox（）方法返回 MsgboxResult < a href = https://docs.microsoft.com/zh-cn/dotnet/csharp/language-reference/keywords/enum rel = noreferrer>枚举，请检查该方法返回的值：

The MsgBox() method is returning MsgboxResult Enumeration, check the value that the method returns:

Public Sub MsgBoxExample()
    Dim result As MsgBoxResult = Nothing
    Dim chc As Integer

    result = MsgBox("click something...", vbYesNo, "example")
    If result = MsgBoxResult.Yes Then
        chc = 1
    ElseIf result = MsgBoxResult.No Then
        chc = 0
    End If
    MsgBox(chc)
End Sub
