如何拆分字符串以获取文件名？

Question

I am trying to split the string. Here is the string.

string fileName =   "description/ask_question_file_10.htm"

I have to remove "description/" and ".htm" from this string. So the result I am looking for "ask_question_file_10". I have to look for "/" and ".htm" I appreciate any help.

Answer 1

You can use the Path.GetFileNameWithoutExtension Method :

string fileName = "description/ask_question_file_10.htm";

string result = Path.GetFileNameWithoutExtension(fileName);
// result == "ask_question_file_10"

Answer 2

string fileName = Path.GetFileNameWithoutExtension("description/ask_question_file_10.htm")

Answer 3

try

string myResult = fileName.SubString (fileName.IndexOf ("/") + 1);
if ( myResult.EndsWith (".htm" ) )
   myResult = myResult.SubString (0, myResult.Length - 4);

IF it is really a path then you can use

string myResult = Path.GetFileNameWithoutExtension(fileName);
