Char.IsLowSurrogate Method (Char)


Indicates whether the specified Char object is a low surrogate.

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

static member IsLowSurrogate : 
        c:char -> bool


Type: System.Char

The character to evaluate.

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 point, UTF-16 encoding allows abstract characters to be represented using two 16-bit code points, which is known as a surrogate pair. The second element in this pair is the low surrogate. Its code point 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.
