Represents a variable-length stream of characters to be stored in or retrieved from the database. SqlString has a different underlying data structure from its corresponding .NET Framework String data type.
Namespace:
System.Data.SqlTypes
Assembly:
System.Data (in System.Data.dll)
Visual Basic (Declaration)
<SerializableAttribute> _

Implements INullable, IComparable, IXmlSerializable
Dim instance As SqlString

public value class SqlString : INullable,
IComparable, IXmlSerializable
JScript supports the use of structures, but not the declaration of new ones.
String always uses the default CultureInfo from the current thread, but SqlString contains its own locale Id and compare flags. The comparison result of two SqlString structures is independent of operating system and current thread locale.
When you use SqlString comparison operators, note that if the LCIDs of arguments are different, comparison functions throw an exception because they cannot be compared. For example, the statement
SqlString mySqlString = new SqlString("abc");
is equivalent to
SqlString mySqlString = new SqlString("abc", CultureInfo.CurrentCulture.LCID);
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
