Char.IsLowSurrogate Method (Char)

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public static function IsLowSurrogate(
	c : char
) : boolean


Type: System.Char

A character.

Return Value

Type: System.Boolean
true if the numeric value of the c parameter ranges from U+DC00 through U+DFFF; otherwise, false.

In addition to representing single characters using a 16-bit code unit, UTF-16 encoding allows abstract characters to be represented using two 16-bit code units, which is known as a surrogate pair. The second element in this pair is the low surrogate. Its code unit can range from U+DC00 to U+DFFF. An individual surrogate has no interpretation of its own; it is meaningful only when used as part of a surrogate pair.

The following code example demonstrates the IsHighSurrogate, IsLowSurrogate, and IsSurrogatePair methods.
