Ｃ＃如何取字符串的后几码

[libertyang]

假设　string a = "1A2C.5CFB.XXXXX.BUFFER"
想从a中取出后６码＂BUFFER＂,
有啥简单的方法么？

注：XXXXX　　有几码是不固定的

[mohugomohu]

string[] arr = a.Split(

[ITJaneLiu]

string a = "1A2C.5CFB.XXXXX.BUFFER"
string []str=a.Split(',');
str[3]就是你要的结果.

[zhujiazhi]

a = a.SubString(a.Length - 6);
or
string[] items = a.Split('.');
a = items[items.Length -1];

string a = "1A2C.5CFB.XXXXX.BUFFER";
string str = a.Substring(a.Length - 6);

[PandaIT]

string pandait = "1A2C.5CFB.XXXXX.BUFFER";
Console.WriteLine(pandait.Substring(pandait.LastIndexOf(".")+1));

[zhengkai85]

char[] c = a.ToCharArray();
for (int i = c.Length-6 ;i<c.Length ;i++ )
{
label1.Text += c[i];
}

这个正确

[liherun]

哈

[mr_zhang_live]

string a = "1A2C.5CFB.XXXXX.BUFFER";
string st = a.Substring(a.LastIndexOf(".")+1, 6);

[JackLeiMM]

string a = "1A2C.5CFB.XXXXX.BUFFER";
string str = a.Substring(a.Length -a.LastIndexOf("."));

[回忆是抓不到的月光]

都知道是BUFFER了还取来做什么。。。

[回忆是抓不到的月光]

string st = a.Substring(a.length-6, 6);

[l171147904]

string a = "1A2C.5CFB.XXXXX.BUFFER"
string[] str=a.Split('.');
str[str.length -1]就是你要的结果.

[hhc123]

string a = "1A2C.5CFB.XXXXX.BUFFER";
MessageBox.Show( a.Substring(a.Length-6,6));
这个是固定你要最后6码的东西，
如果.也是固定的话你可以
string a = "1A2C.5CFB.XXXXX.BUFFER";
MessageBox.Show( a.Substring(a.LastIndexOf('.')+1,a.Length-a.LastIndexOf('.')-1));
