Strings.Mid Method (String, Int32, Int32)
Assembly: Microsoft.VisualBasic (in microsoft.visualbasic.dll)
Required. String expression from which characters are returned.
Required. Integer expression. Starting position of the characters to return. If Start is greater than the number of characters in str, the Mid function returns a zero-length string (""). Start is one based.
Optional. Integer expression. Number of characters to return. If omitted or if there are fewer than Length characters in the text (including the character at position Start), all characters from the start position to the end of the string are returned.
Return ValueReturns a string containing a specified number of characters from a string.
For more detailed information, see the Visual Basic topic Mid Function (Visual Basic).
To determine the number of characters in str, use the Len function.
Visual Basic has a Mid function and a Mid statement. These elements both operate on a specified number of characters in a string, but the Mid function returns the characters while the Mid statement replaces the characters. For more information, see Mid Statement.
The MidB function in previous versions of Visual Basic returns a string in bytes rather than characters. It is used primarily for converting strings in double-byte character set (DBCS) applications. All Visual Basic strings are in Unicode, and MidB is no longer supported.
This example uses the Mid function to return a specified number of characters from a string.
