如何获取文本直到字符串中的符号

Question

How to get text before a symbol in string ? Any ideas?

eg acsbkjb/123kbvh/123jh/

get text before first - "/"

Answer 1

尝试这个

string ss = myString.Split('/')[0];

Answer 2

You can use Substring() method to get the required part of the string.

String text="acsbkjb/123kbvh/123jh/";
int index=text.IndexOf('/');  
String text2="";

if(index>=0)
text2=text.Substring(0,index);

Answer 3

得到像

youstring.Substring(0,yourstring.IndexOf('/'));

Answer 4

The IEnumerable approach

  string str = "acsbkjb/123kbvh/123jh/";
  var result = new string(str.TakeWhile(a => a != '/').ToArray());
  Console.WriteLine(result);

If there are no forward slashes this works without need to check the return of IndexOf

EDIT Keep this answer just as an example because the efficiency of this approach is really worse. IndexOf works faster also if you add an if statement to check the return value.

Answer 5

string text = "acsbkjb/123kbvh/123jh/";    
string text2 = text.Substring(0, text.IndexOf("/"));
