对asp.net债务比较的怀疑 [英] doubt in asp.net abt comparison

问题描述

这是我的代码

hi this is my code

adp = new SqlDataAdapter("select tenderamount from tender", con);
       ds = new DataSet();
       adp.Fill(ds, "tender");
       if (ds.Tables["tender"].Rows.Count > 0)
       {
           if (TextBox5.Text > ds.Tables["tender"].Rows[0][1].ToString())
           {
               Response.Redirect("Payment.aspx?BidAmount=" + TextBox5.Text + "&TenderName=" + DropDownList1.Text);
           }
           else
           {
               Label3.Text = "sorry Your bid amount is low";
           }
       }

我想在sql中比较数据形式的文本框和表值，那么只有它会重定向到新页面，请帮助我，我现在就去整理它

i want to compare the data form textbox and table value in sql then only it will redirect to new page, pls help me, i wnt to finsh it now

推荐答案

if (TextBox5.Text > ds.Tables["tender"].Rows[0][1].ToString()).您正在使用>运算符比较两个字符串.这可能无法正常工作.

如果这些值是数字，请使用

if (Convert.ToInt32(TextBox5.Text) > Convert.ToInt32(ds.Tables["tender"].Rows[0][1].ToString()))

if (TextBox5.Text > ds.Tables["tender"].Rows[0][1].ToString()). You are comparing two string with > operator. This may not work well.

If those values are numbers then use

if (Convert.ToInt32(TextBox5.Text) > Convert.ToInt32(ds.Tables["tender"].Rows[0][1].ToString()))
