/*
    string sIn = "FF";
    textBox5.Text = "";
    foreach (char c in sIn) //用字符编码
    {
        textBox5.Text  = ((int)c).ToString();
    }
 * //textBox5.Text = Convert.ToDecimal("2.9853").ToString("0.00"); //保留小数
  变量.ToString()       
   字符型转换 转为字符串 
   12345.ToString("n");        //生成   12,345.00 
   12345.ToString("C");        //生成 ¥12,345.00 
   12345.ToString("e");        //生成 1.234500e 004 
   12345.ToString("f4");        //生成 12345.0000 
   12345.ToString("x");         //生成 3039 (16进制) 
   12345.ToString("p");         //生成 1,234,500.00%
 * 字串变量.Replace("子字串","替换为") 
     字串替换 
     如: 
     string str="中国"; 
     str=str.Replace("国","央"); //将国字换为央字 
     Response.Write(str);     //输出结果为“中央”
 * 一、
1、取字符串的前i个字符
(1)string str1=str.Substring(0,i);
(2)string str1=str.Remove(i,str.Length-i);
2、去掉字符串的前i个字符
string str1=str.Remove(0,i);
string str1=str.SubString(i);
3.提取字符串中的第i个字符开始的长度为j的字符串;
string str = "GTAZB_JiangjBen_123";
int start=3,length=8; 
Console.WriteLine(str.Substring(start-1, length));
4、从右边开始去掉i个字符:
string str1=str.Substring(0,str.Length-i);
string str1=str.Remove(str.Length-i,i);
5、
6 、如果字符串中有"abc"则替换成"ABC"
   str=str.Replace("abc","ABC");
7、c#截取字符串最后一个字符的问题!!!!!!!!!!!!!!!!!!!!!
str1.Substring(str1.LastIndexOf(",") 1);
8、C# 截取字符串最后一个字符
k = k.Substring(k.Length-1, 1);

小贴士

感谢您为本站写下的评论,您的评论对其它用户来说具有重要的参考价值,所以请认真填写。

  • 类似“顶”、“沙发”之类没有营养的文字,对勤劳贡献的楼主来说是令人沮丧的反馈信息。
  • 相信您也不想看到一排文字/表情墙,所以请不要反馈意义不大的重复字符,也请尽量不要纯表情的回复。
  • 提问之前请再仔细看一遍楼主的说明,或许是您遗漏了。
  • 请勿到处挖坑绊人、招贴广告。既占空间让人厌烦,又没人会搭理,于人于己都无利。
