问题描述

任何人都可以更正以下代码.我正在尝试限制字符串中的数字值.

我遇到以下错误在'='附近的语法不正确".

我是VB .NET的新手.请帮我解决这个问题.

Hi,

Can anybody correct the below code. I am trying to restrict the numeric values in a string.

I am facing the following error "Incorrect syntax near ''=''".

I am new in VB .NET. Please help me to solve this.

If po_Country.cn_name = "" Then
            o_General.lp_AddPipe(ls_ErrMsg)
            ls_ErrMsg = ls_ErrMsg + "Country Name can not be empty."
        ElseIf po_Country.cn_name.Contains("0-9") Then
            o_General.lp_AddPipe(ls_ErrMsg)
            ls_ErrMsg = ls_ErrMsg + "Country name can not contain numeric values."
        End If

问候，
Srikar

推荐答案

If po_Country.cn_name = "" Then
    o_General.lp_AddPipe(ls_ErrMsg)
    ls_ErrMsg = ls_ErrMsg + "Country Name can not be empty."
ElseIf po_Country.cn_name.Contains("0-9") Then
    o_General.lp_AddPipe(ls_ErrMsg)
    ls_ErrMsg = ls_ErrMsg + "Country name can not contain numeric values."
End If

通过键入以下命令使它看起来像这样:

I made it look like that by typing this:

<pre lang="vb">If po_Country.cn_name = "" Then
    o_General.lp_AddPipe(ls_ErrMsg)
    ls_ErrMsg = ls_ErrMsg + "Country Name can not be empty."
ElseIf po_Country.cn_name.Contains("0-9") Then
    o_General.lp_AddPipe(ls_ErrMsg)
    ls_ErrMsg = ls_ErrMsg + "Country name can not contain numeric values."
End If</pre>

结束我本可以为您做的，但是我宁愿教您如何做，而不是为您做.

I could have done that for you, but I would rather teach you how to do it than do it for you.
