.NET Framework (current version)
 

Indicates whether the specified character has a surrogate code unit.

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

C#
C++
F#
VB
Copy 
public:
static bool IsSurrogate(
	wchar_t c
)

Parameters

c
Type: System::Char

The Unicode character to evaluate.

Return Value

Type: System::Boolean

true 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.

C#
C++
VB
Copy 
using namespace System;
int main()
{

   // - escape params specifying Unicode not implemented in v7.0
   Console::WriteLine( Char::IsSurrogate( 'a' ) ); // Output: "False"
}
