I am reading shpae files and I would like to preapare a single string og particular attribute from shape file for all feature.
e.g. If shape file atrributes are
ID COUNTY_NAME POP
---------------------------------
1 ABC 100
2 XXX 1000
3 DEF 101
4 XYZ 500
I would like to prepare a string of COUNTY_NAME attribute of all features like
string = "ABC,XXX,DEF,XYZ"
How can I achieve this.
