Char.IsSurrogatePair(String, Int32) Method in C#
The Char.IsSurrogatePair() method in C# is used to indicate whether two adjacent Char objects at a specified position in a string form a surrogate pair.
Syntax
Following is the syntax −
public static bool IsSurrogatePair (string str, int index);
Above, the string str is a string, whereas the index is the starting position of the pair of characters to evaluate within str.
Example
Let us now see an example to implement the Char.IsSurrogatePair() method −
using System;
public class Demo {
public static void Main(){
string str = new String(new char[] { 'k', 'm', 'g', 't', '\uD800' });
bool res = Char.IsSurrogatePair(str, 4);
if (res)
Console.WriteLine("Contains Surrogate pair!");
else
Console.WriteLine("Does not contain Surrogate pair!");
}
}Output
This will produce the following output −
Does not contain Surrogate pair!
Example
Let us now see another example −
using System;
public class Demo {
public static void Main(){
string str = new String(new char[] { 'k','l','a', '\uD800', '\uDC00' });
bool res = Char.IsSurrogatePair(str, 3);
if (res)
Console.WriteLine("Contains Surrogate pair!");
else
Console.WriteLine("Does not contain Surrogate pair!");
}
}Output
This will produce the following output −
Contains Surrogate pair!
