hi,
you need to make class like
public class Vehical
{
string key=string.Empty;
string value1=string.Empty;
int value2=0;
string value3=string.Empty;
string value4=string.Empty;
}
And now make list object of class vehical
like,
list<vehical> obj;
you can add,update,delete,find and many more using this and lamda expression.
hopes this work for u...
