SqlString Structure

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. 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.

Namespace: System.Data.SqlTypes
Assembly: System.Data (in system.data.dll)

public struct SqlString : INullable, IComparable, IXmlSerializable
/** @attribute SerializableAttribute() */ 
public final class SqlString extends ValueType implements INullable, IComparable, 
JScript suports the use of structures, but not the declaration of new ones.

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.
