如果不满足else条件,但仍在内部运行代码

web-config if-statement asp.net c#

CodeMan · 技术社区 · 9 年前

这是我遇到的一个非常不寻常的问题,我的if-else if条件不起作用: 1) 我正在从web.config读取值

string validuserlist = ConfigurationManager.AppSettings["Quality"].ToString();
string safetylist = ConfigurationManager.AppSettings["Safety"].ToString();
string supervisorlist = ConfigurationManager.AppSettings["Supervisors"].ToString();

2) 我正在检查当前用户是否在上述列表中,以及工作订单类型是否为gridview中的类型:

如您所见,上述条件失败,但仍运行该代码:

如果您需要任何代码或逻辑理解,请在标记此问题之前询问。

以下是我的情况:

if (validuserlist.ToLower().Trim().IndexOf(username.ToLower().Trim()) != -1 && TextBox102.Text == "Quality")
{
    CheckQuality();
    if (flag == true)
    {
        ModalPopupExtender1.Show();
        TextBox TextBox1 = (TextBox)DetailsView1.FindControl("TextBox30");
        TextBox TextBox2 = (TextBox)DetailsView1.FindControl("TextBox91");
        TextBox1.Enabled = true;
        TextBox2.Enabled = true;
        DetailsView1.Visible = true;
        ModalPopupExtender2.Show();
        DetailsView2.Visible = true;
    }
    else
    {
        string message = "your user id does not have permissions to signoff WorkOrders of type" + " " + TextBox102.Text + ", please contact IT Support for Permission";
        System.Text.StringBuilder sb = new System.Text.StringBuilder();
        sb.Append("<script type = 'text/javascript'>");
        sb.Append("window.onload=function(){");
        sb.Append("alert('");
        sb.Append(message);
        sb.Append("')};");
        sb.Append("</script>");
        ClientScript.RegisterClientScriptBlock(this.GetType(), "alert", sb.ToString());
    }
}
else if (safetylist.ToLower().Trim().IndexOf(username.ToLower().Trim()) != -1 && TextBox102.Text == "Safety")
{
    CheckSafety();
    if (flag == true)
    {
        ModalPopupExtender1.Show();
        TextBox TextBox1 = (TextBox)DetailsView1.FindControl("TextBox30");
        TextBox TextBox2 = (TextBox)DetailsView1.FindControl("TextBox91");
        TextBox1.Enabled = true;
        TextBox2.Enabled = true;
        DetailsView1.Visible = true;
        ModalPopupExtender2.Show();
        DetailsView2.Visible = true;
    }
    else
    {
        string message = "your user id does not have permissions to signoff WorkOrders of type" + " " + TextBox102.Text + ", please contact IT Support for Permission";
        System.Text.StringBuilder sb = new System.Text.StringBuilder();
        sb.Append("<script type = 'text/javascript'>");
        sb.Append("window.onload=function(){");
        sb.Append("alert('");
        sb.Append(message);
        sb.Append("')};");
        sb.Append("</script>");
        ClientScript.RegisterClientScriptBlock(this.GetType(), "alert", sb.ToString());
    }
}
else if (supervisorlist.ToLower().Trim().IndexOf(username.ToLower().Trim()) != -1 && TextBox102.Text == "Safety" || TextBox102.Text == "Quality" || TextBox102.Text == "General")
{
    if (flag == false)
    {
        ModalPopupExtender1.Show();
        TextBox TextBox1 = (TextBox)DetailsView1.FindControl("TextBox30");
        TextBox TextBox2 = (TextBox)DetailsView1.FindControl("TextBox91");
        TextBox1.Enabled = true;
        TextBox2.Enabled = true;
        DetailsView1.Visible = true;
        ModalPopupExtender2.Show();
        DetailsView2.Visible = true;
    }
    else
    {
        string message = "your user id does not have permissions to signoff WorkOrders of type" + " " + TextBox102.Text + ", please contact IT Support for Permission";
        System.Text.StringBuilder sb = new System.Text.StringBuilder();
        sb.Append("<script type = 'text/javascript'>");

        sb.Append("alert('");
        sb.Append(message);
        sb.Append("')};");
        sb.Append("</script>");
        ClientScript.RegisterClientScriptBlock(this.GetType(), "alert", sb.ToString());
    }
}

因此,在注释中发现一些新信息后,我们可以解决if条件的问题。

else if (supervisorlist.ToLower().Trim().IndexOf(username.ToLower().Trim()) != -1 && TextBox102.Text == "Safety" || TextBox102.Text == "Quality" || TextBox102.Text == "General")

这基本上是说:

如果监督员在此列表中,且TextBox102等于“安全”,则运行条件。或者,如果TextBox102等于“质量”,则运行条件。或者,如果TextBox102等于“常规”,则运行条件。

似乎您想知道主管是否在该列表中,以及文本框是否等于其中一个,因此,@Aidin建议,您的if语句应该如下所示:

else if (supervisorlist.ToLower().Trim().IndexOf(username.ToLower().Trim()) != -1 && (TextBox102.Text == "Safety" || TextBox102.Text == "Quality" || TextBox102.Text == "General"))

请注意,文本框的每个复选框周围都有一组额外的括号。这将您的IF语句转换为:

如果主管在列表中,且TextBox102=安全或TextBox1102=一般或TextBox202=质量,则运行条件。

(编辑:实际上,这里有点像忍者丹·奥洛夫斯基(Dan Orlovsky),因为在我发布这篇文章的同时,他在评论中找到了答案。他的答案更详细。)

supervisorlist.ToLower().Trim().IndexOf(username.ToLower().Trim()) != -1 
    && TextBox102.Text == "Safety" 
    || TextBox102.Text == "Quality" 
    || TextBox102.Text == "General"

supervisorlist.ToLower().Trim().IndexOf(username.ToLower().Trim()) != -1 
    && (TextBox102.Text == "Safety" 
        || TextBox102.Text == "Quality" 
        || TextBox102.Text == "General")
