字符串处理，很简单的问题。（菜鸟级提问）

[liuxibei1987]

比如这样一个字符串 E:\aaa\bbb\ccc\ddd\e.txt
如何操作这个字符串得到e.txt这样一个字符处， 也就是说要得分最右边一个\后面的字符串

[ztwz]

获取最后一个\位置+1就ok了。自己查msdn

who can help me？

如果是文件方式的使用

FileInfo _FileInfo = new FileInfo(@"E:\aaa\bbb\ccc\ddd\e.txt");

_FileInfo.Name; //e.txt

_FileInfo.Directory.FullName; //E:\aaa\bbb\ccc\ddd\

[jingsong2008]

string a = E:\aaa\bbb\ccc\ddd\e.txt ;
string[] str = a.split('\'),然后循环得出

[jingsong2008]

注意转义

[liuxibei1987]

3L的string[] str = a.split('\'), 这样写会报错的， 提示字符中出现换行符反正这个地方的\这个符号不能直接写进去啊

[MOmo400]

string path = @"E:\aaa\bbb\ccc\ddd\e.txt ";
FileInfo info = new FileInfo(path);

path = path.Remove(0, info.DirectoryName.Length + 1);
MessageBox.Show(path);

Regex re = new Regex(@".*\\(.*)", RegexOptions.Singleline);
string str = @"E:\aaa\bbb\ccc\ddd\e.txt";
Match mt = re.Match(str);
if (mt.Success)
{
    Console.WriteLine(mt.Groups[1].ToString());
}

[LoveLife_Go]

string str="E:\aaa\bbb\ccc\ddd\e.txt";
            int index = str.LastIndexOf("\\")+1;
            str = str.Substring(index);

[编程有钱人了]

string sss = @"E:\aaa\bbb\ccc\ddd\e.txt ";
string test = sss.Substring(sss.LastIndexOf("\\")+1);

[yinseguiji]

string x=@"E:\aaa\bbb\ccc\ddd\e.txt ";

string result=x.split('\\')[x.split('\\').length-1];

[liuxibei1987]

我自己也做出来了， 不过用split分割在取最后一个，好复杂
最佳答案还是用substring（lastindexof+1）
多谢各位

[HDNGO]

或者~~

Match mt = Regex.Match(@"E:\aaa\bbb\ccc\ddd\e.txt", @"[^\\]+$");
Console.WriteLine(mt.Value);

办法比较笨,但能实现.

                string strPath = objDialog.FileName;
                strPath = MSTextFileProcess.ConverseString(strPath);
 
                //Get the DBScript file's name
                int iIndex = strPath.IndexOf("\\");
                if (iIndex != -1)
                {
                    strPath = strPath.Substring(0, iIndex);
                    this.txtFileName.Text = MSTextFileProcess.ConverseString(strPath);
                }
                else
                    this.txtFileName.Text = objDialog.FileName;
