Char.IsSurrogate Method (Char)
Indicates whether the specified character has a surrogate code unit.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- c
- Type: System.Char
The Unicode character to evaluate.
Return Value
Type: System.Booleantrue if c is either a high surrogate or a low surrogate; otherwise, false.
A surrogate is a Char object with a UTF-16 code unit in the range from U+D800 to U+DFFF. Each character with a code unit in this range belongs to the UnicodeCategory.Surrogate category. The individual surrogate code unit has no interpretation of its own, but has meaning only when used as part of a surrogate pair. For more information about surrogate pairs, see the Unicode Standard at the Unicode home page.
The following example demonstrates the IsSurrogate method.
using System; public class IsSurrogateSample { public static void Main() { string str = "\U00010F00"; // Unicode values between 0x10000 and 0x10FFF are represented by two 16-bit "surrogate" characters Console.WriteLine(Char.IsSurrogate('a')); // Output: "False" Console.WriteLine(Char.IsSurrogate(str, 0)); // Output: "True" } }
