字符替换问题.

Question

string afff = "P1A-P2R-P3D-P5T()-1002" ;
        我想把afff中的()和-都去掉变成P1AP2RP3DP5T1002 这样的格式,怎么做?
string changeaff=afff.Replace('-','');会报错
string changeaff=afff.Replace('-',"".tochararray);也会报错.
还有怎样同时替换()-这三个符号呢?

Answer 1

string changeaff=afff.Replace('-','');
-->
string changeaff=afff.Replace("-","");

Answer 2

string changeaff=afff.Replace("-","");
changeaff=changeaff.Replace("()","");

Answer 3

分开替换！
string changeaff=afff.Replace("-","");
changeaff=changeaff.Replace("()","");
可以吧！

Answer 4

char [] tmpArray  = afff.ToCharArray();
            string tmpStr = string.Empty;
            foreach (char tmpChar in tmpArray)
            {
                if (tmpChar == '-' || tmpChar == '(' || tmpChar == ')' || tmpChar == ' ')
                    continue;
                tmpStr += tmpChar.ToString();
            }

Answer 5

一般的用string的Replace就可以了
string changeaff=afff.Replace("-","");
changeaff=afff.Replace("(","");
changeaff=afff.Replace(")","");如果想一次性全部替换，也可以用正则，不过一般应用没有直接用string的方法效率高
using System.Text.RegularExpressions;string changeaff= Regex.Replace(afff, @"[-\(\)]", "");

Answer 6

汗，直接Replace的应该这样写
string changeaff=afff.Replace("-","");
changeaff=changeaff.Replace("(","");
changeaff=changeaff.Replace(")","");

Answer 7

string changeaff= System.Text.RegularExpressionsRegex.Replace(afff, @"[-\(\)]", "");

Answer 8

string changeaff=afff.Replace('-','');
-->
string changeaff=afff.Replace("-","");

Answer 9

using System.Text;
using System.Text.RegularExpressions;
afff = Regex.Replace(afff, "(|)|-","");
