Char.IsHighSurrogate(String, Int32) Method in C#
The Char.IsHighSurrogate() method in C# indicates whether the Char object at the specified position in a string is a high surrogate.
Syntax
Following is the syntax −
public static bool IsHighSurrogate (string str, int index);
Above, str is a string, whereas the index is the position of the character to evaluate in str.
Example
Let us now see an example to implement the Char.IsHighSurrogate() method −
using System;
public class Demo {
public static void Main(){
string str = new String(new char[] { 'k', 'm', 'g', 't', '\uD800' });
bool res = Char.IsHighSurrogate(str, 4);
if (res)
Console.WriteLine("Contains High Surrogate value!");
else
Console.WriteLine("Does not contain High Surrogate value!");
}
}Output
This will produce the following output −
Contains High Surrogate value!
Example
Let us now see another example −
using System;
public class Demo {
public static void Main(){
string str = new String(new char[] { 'k', 'm', 'g', 't', '\uD800' });
bool res = Char.IsHighSurrogate(str, 2);
if (res)
Console.WriteLine("Contains High Surrogate value!");
else
Console.WriteLine("Does not contain High Surrogate value!");
}
}Output
This will produce the following output −
Does not contain High Surrogate value!
