Strings.Mid Method (String, Int32)

Returns a string containing a specified number of characters from a string.

Namespace:  Microsoft.VisualBasic
Assembly:  Microsoft.VisualBasic (in Microsoft.VisualBasic.dll)

public static string Mid(
	string str,
	int Start
)

Parameters

str
Type: System.String

Required. String expression from which characters are returned.

Start
Type: System.Int32

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.

Return Value

Type: System.String
Returns 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.

NoteNote:

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.

' Creates text string. 
Dim TestString As String = "Mid Function Demo" 
' Returns "Mid". 
Dim FirstWord As String = Mid(TestString, 1, 3)
' Returns "Demo". 
Dim LastWord As String = Mid(TestString, 14, 4)
' Returns "Function Demo". 
Dim MidWords As String = Mid(TestString, 5)
