How to read text file based on key values

hi,

i have text file ini file, how read text file based on keys

i need values after "="  symbol

here example lines.

lbldays1=days
lblinhex=in hexadecimal notation
information=information
lblhjunk=junk e-mail folder excluded selected mailboxes
lblhfqdn=fully qualified domain name. find fqdn, open exchange system manager, expand recipeints, open recipient policies, double click on default policy, in properties windows, navigate email addresses(policy) tab, find out default smtp entry(the highlighted one), fqdn(without first @ symbol)
lblftypeincluded=file types included
lbl60000=(60-6000)
lblexchusername=username
lbl10000=(1-10000)

hi,

you use code above. 

using system; using system.io; using system.collections;  public class iniparser {     private hashtable keypairs = new hashtable();     private string inifilepath;      private struct sectionpair     {         public string section;         public string key;     }      /// <summary>     /// opens ini file @ given path , enumerates values in iniparser.     /// </summary>     /// <param name="inipath">full path ini file.</param>     public iniparser(string inipath)     {         textreader inifile = null;         string strline = null;         string currentroot = null;         string[] keypair = null;          inifilepath = inipath;          if (file.exists(inipath))         {             try             {                 inifile = new streamreader(inipath);                  strline = inifile.readline();                  while (strline != null)                 {                     strline = strline.trim().toupper();                      if (strline != "")                     {                         if (strline.startswith("[") && strline.endswith("]"))                         {                             currentroot = strline.substring(1, strline.length - 2);                         }                         else                         {                             keypair = strline.split(new char[] { '=' }, 2);                              sectionpair sectionpair;

                            sectionpair.key = keypair[0];                              if (keypair.length > 1)                                 value = keypair[1];                              keypairs.add(sectionpair, value);                         }                     }                      strline = inifile.readline();                 }              }             catch (exception ex)             {                 throw ex;

                     if (tmpvalue != null)                         tmpvalue = "=" + tmpvalue;                      strtosave += (sectionpair.key + tmpvalue + "\r\n");                 }             }              strtosave += "\r\n";

this implementation of class above:

public class testparser {     public static void main()     {         iniparser parser = new iniparser(@"c:\test.ini");          string newmessage;          newmessage = parser.getsetting("appsettings", "msgpart1");         newmessage += parser.getsetting("appsettings", "msgpart2");         newmessage += parser.getsetting("punctuation", "ex");          //returns "hello world!"         console.writeline(newmessage);         console.readline();     } }
