The common supporting VB.NET String Function are Asc, AscW, Chr, ChrW, Filter, Format, FormatCurrency, FormatDateTime, FormatNumber, FormatPercent, InStr, InStrRev, Join, LCase, Left, Len, LSet, LTrim, Mid, Replace, Right, RSet, RTrim, Space, Split, StrComp, StrConv, StrDup, StrReverse, Trim, UCase

String Functions

The following table lists the functions that Visual Basic provides to search and manipulate strings.

.NET Framework method	Description
Asc, AscW	Returns an Integer value representing the character code corresponding to a character.
Chr, ChrW	Returns the character associated with the specified character code.
Filter	Returns a zero-based array containing a subset of a String array based on specified filter criteria.
Format	Returns a string formatted according to instructions contained in a format String expression.
FormatCurrency	Returns an expression formatted as a currency value using the currency symbol defined in the system control panel.
FormatDateTime	Returns a string expression representing a date/time value.
FormatNumber	Returns an expression formatted as a number.
FormatPercent	Returns an expression formatted as a percentage (that is, multiplied by 100) with a trailing % character.
InStr	Returns an integer specifying the start position of the first occurrence of one string within another.
InStrRev	Returns the position of the first occurrence of one string within another, starting from the right side of the string.
Join	Returns a string created by joining a number of substrings contained in an array.
LCase	Returns a string or character converted to lowercase.
Left	Returns a string containing a specified number of characters from the left side of a string.
Len	Returns an integer that contains the number of characters in a string.
LSet	Returns a left-aligned string containing the specified string adjusted to the specified length.
LTrim	Returns a string containing a copy of a specified string with no leading spaces.
Mid	Returns a string containing a specified number of characters from a string.
Replace	Returns a string in which a specified substring has been replaced with another substring a specified number of times.
Right	Returns a string containing a specified number of characters from the right side of a string.
RSet	Returns a right-aligned string containing the specified string adjusted to the specified length.
RTrim	Returns a string containing a copy of a specified string with no trailing spaces.
Space	Returns a string consisting of the specified number of spaces.
Split	Returns a zero-based, one-dimensional array containing a specified number of substrings.
StrComp	Returns -1, 0, or 1, based on the result of a string comparison.
StrConv	Returns a string converted as specified.
StrDup	Returns a string or object consisting of the specified character repeated the specified number of times.
StrReverse	Returns a string in which the character order of a specified string is reversed.
Trim	Returns a string containing a copy of a specified string with no leading or trailing spaces.
UCase	Returns a string or character containing the specified string converted to uppercase.

You can use the Option Compare statement to set whether strings are compared using a case-insensitive text sort order determined by your system's locale (Text) or by the internal binary representations of the characters (Binary). The default text comparison method is Binary.
