Document Summary

I(cid:374) the for . ne(cid:454)t loop, the (cid:272)ou(cid:374)ter (cid:448)aria(cid:271)le i (cid:272)a(cid:374) ha(cid:448)e a(cid:374)(cid:455) (cid:374)a(cid:373)e. In the for each loop =, the looping variable age can have any name. The primary difference between both types of loops is that in a for each loop, no changes can be made in the values of the elements of the array. If no characters is specified, the space character will be used as the delimiter. The reverse of the split fmethod is the join function. Join concentrates the elements of a string array into a string containing the elements separated by a specified delimiter. Linq stands for language integrated query: a query is a request for information, note: option infer must e set to on in order to use linq. The values in the sequence can be converted to an array, displayed in a list box, or written to a text file. A query variable is not an array variable.
