Tab separated string split in C# -

there several stackoverflow question posted none of them works me.

i have string say

   string str = "15.24\t7.28\t6.04\t5.0";

in app.config, define key value

   <add key="delimiter" value="\t"/>

in program, have this

 string delimiter = configurationmanager.appsettings["delimiter"];   string[] parsedvalues = str.split(delimiter.tochararray());

while debugging find delimiter gets changed "\t" , doesn't split string.

i have tried changing app.config

 <add key="delimiter" value=@"\t"/>

but gives error.

even following gives error.

 <add key="delimiter" value='\t' />

any appreciated.

try replacing \t 	 in config file. in xml files tab character represented 	.
