C#回车替换为其他字符

using System.Text.RegularExpressions;//添加上这个

private string displace(string myStr, string displaceA, string displaceB)  //定义替换函数，返回的类型为string,   myStr为需修改的字符串，

                                                                                                     //displaceA需替换掉的字符

                                                                                                     //displaceB需替换成的字符

        {
            string[] strArrayA = Regex.Split(myStr, displaceA);  //Regex需使用using System.Text.RegularExpressions;以displaceA为分割成数组

            for (int i = 0; i < strArrayA.Length - 1; i++)
            {
                strArrayA[i] += displaceB;//数组成员循环添加“需替换的字符”

            }
            string returnStr = "";
            foreach (string var in strArrayA)
            {
                returnStr += var;//将数组循环添加成字符串
            }
            return returnStr;
        }
