SqlString

SqlString

System.Data.SqlTypes (system.data.dll) struct

A structure that represents a variable-length stream of characters . You can use this structure for the following SQL Server data types: char , nchar , varchar , nvarchar , ntext , text , and sysname . You can configure how SqlString instances should be compared by setting a combination of values from the SqlCompareOptions enumeration for the SqlCompareOptions property.

The built-in methods include one for string concatenation ( Concat( ) ). To determine the geographical locale and language for this structure, use the LCID property, and for information about culture-specific settings (such as culture name , writing system, and calendar) use the CultureInfo property.
