无法在c#中创建所需字符串

本文关键字：字符串创建 | 更新日期: 2023-09-27 18:05:47

我有以下代码

while (i<(count-1))
{                    
   string temp = null;       
   if (i == 0)
   {
        temp = "'"" + arry[i] + "'"";
   }
   else
   {
        temp = "," + "'""+arry[i]+"'"";
   }
   demo = demo + temp;
   i++;
}

这是给出字符串demo

demo = "'"0'",'"1'",'"2'",'"3'",'"4'""

但我想在格式demo= "0","1","2","3","4"

无法在c#中创建所需字符串

IDE将显示转义字符('")，但当使用字符串时，它们将不存在

尝试将其写入控制台并检查是否正确

我更喜欢使用这样的代码:

var demo = string.Join(
    ",", 
    Enumerable.Range(1, count)
        .Select(n => string.Format("'"{0}'"", n)));

把它分解一下…

Enumerable.Range(1, count) //Gives a list of integers from 1 to count
.Select(n => string.Format("'"{0}"'"", n) //Surrounds each integer with double quotes
string.Join(...) //Joins the strings above using the comma

字符串模板={0}'"'"";

        while (i < (count - 1))
        {
            string temp = null;
            if (i == 0)
            {
                temp = string.Format(template, arry[i]);
            }
            else
            {
                temp = "," + string.Format(template, arry[i]);
            }
            demo = demo + temp;
            i++;
        }
