The Split () function returns a Variant containing an array of String, and then it copies the entire array into a new array of String. VB creates what is called a string descriptor for each dynamic string. It also uses the GetUpperBound method to determine the number of elements in each dimension of a multidimensional array. You initialize an array variable by including an array literal in a New clause and specifying the initial values of the array. NET: I have a long string like this dim LongString as String = "123abc456def789ghi" And I want to split it into a string array. Unlike many modern languages, C does not have a built-in string data type.
