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 String data type.

Remarks

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);

Constructors

SqlString(Int32, SqlCompareOptions, Byte[], Boolean)	Initializes a new instance of the SqlString class.
SqlString(Int32, SqlCompareOptions, Byte[], Int32, Int32, Boolean)	Initializes a new instance of the SqlString class.
SqlString(Int32, SqlCompareOptions, Byte[], Int32, Int32)	Initializes a new instance of the SqlString class.
SqlString(Int32, SqlCompareOptions, Byte[])	Initializes a new instance of the SqlString structure using the specified locale id, compare options, and data.
SqlString(String, Int32, SqlCompareOptions)	Initializes a new instance of the SqlString structure using the specified string, locale id, and compare option values.
SqlString(String, Int32)	Initializes a new instance of the SqlString structure using the specified string and locale id values.
SqlString(String)	Initializes a new instance of the SqlString structure using the specified string.

Fields

BinarySort	Specifies that sorts should be based on a characters numeric value instead of its alphabetical value.
BinarySort2	Specifies that sorts should be based on a character's numeric value instead of its alphabetical value.
IgnoreCase	Specifies that SqlString comparisons should ignore case.
IgnoreKanaType	Specifies that the string comparison must ignore the Kana type.
IgnoreNonSpace	Specifies that the string comparison must ignore non-space combining characters, such as diacritics.
IgnoreWidth	Specifies that the string comparison must ignore the character width.
Null	Represents a DBNull that can be assigned to this instance of the SqlString structure.

Properties

CompareInfo	Gets the CompareInfo object that defines how string comparisons should be performed for this SqlString structure.
CultureInfo	Gets the CultureInfo structure that represents information about the culture of this SqlString object.
IsNull	Indicates whether this SqlString structure is null.
LCID	Specifies the geographical locale and language for the SqlString structure.
SqlCompareOptions	A combination of one or more of the SqlCompareOptions enumeration values that represent the way in which this SqlString should be compared to other SqlString structures.
Value	Gets the string that is stored in this SqlString structure. This property is read-only.
