如何在asp.net中修剪字符串 [英] how to trim string in asp.net

问题描述

如何在asp.net中修剪字符串...
我的问题是这个...

str2 = str2 + "," + CheckBoxList2.Items[i].Text;

如果我选择了chekbox的5个项目，则在最后一个项目之后添加，但我不希望这样做，则在字符串的最后插入int. />

 如果(str2 .Length >   1 );
} 

以这种形式使用它希望可以让您清楚明白

 如果((i +  1 )== CheckBoxList2.Items.Count )
          str2 + = CheckBoxList2.Items [i] .Text;
      其他
          str2 + = CheckBoxList2.Items [i] .Text + " ; 

计算List的长度并应用if条件，如果变量小于长度，则应用，"，否则，如果其等于长度，则跳过，"

解决方案

try this its simple

if (str2 .Length > 0)
{
str2 = str2 .Remove(str2 .Length - 1);
}

Use it in this form hope makes it clear to you

if ((i + 1) == CheckBoxList2.Items.Count)
          str2 +=  CheckBoxList2.Items[i].Text;
      else
          str2 += CheckBoxList2.Items[i].Text + ", ";

Calculate the length of the List and apply the if condition, if the variable is less than the length then apply "," else if its equal to the length then skip the ","
