Replaces a part of one string with anotherĬoncatenates one or more strings into one stringĭelete a section of characters from a stringĬopy bytes of data from a source to a destinationĬreates a string with one character repeated many times These sub-arrays are thereby shared by both the source and target arrays. After the copy, the target array elements continue to point to the sub-arrays of the source array. The elements of all but the final dimension of an array are all pointers to sub-arrays that make up the whole array. When copying multi-dimensional arrays, only the first dimension is copied. To guarantee copying to the end of the string or array, use the MaxInt constant as the Count value. Less than Count elements if the end of the Source array is encountered before Count elements have been copied.įor string copying, a StartChar less than 1 is treated as 1. Up to Count elements are copied from the StartIndex of the Source array to the returned array. The first element of an array has index = 0. Less than Count characters if the end of the Source string is encountered before Count characters have been copied. Up to Count characters are copied from the StartChar of the Source string to the returned string. The first character of a string has index = 1. In the second, it creates a new array from part of an existing array. In the first, it creates a new string from part of an existing string.
