C# | Uri.CheckSchemeName(String) Method

Last Updated : 11 Jul, 2025

Uri.CheckSchemeName(String) Method is used to determine whether the specified scheme name is valid or not.

Syntax: public static bool CheckSchemeName (string schemeName); Here, it takes the scheme name to validate. Return Value: This method returns a Boolean value true if the scheme name is valid otherwise, false.

Below programs illustrate the use of Uri.CheckSchemeName() Method: Example 1:

csharp

// C# program to demonstrate the
// Uri.CheckSchemeName(string) Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        // Declaring and initializing Uri
        Uri uri = new Uri("https://www.geeksforgeeks.org");

        // Determining the Scheme of the Uri
        string scheme = uri.Scheme;

        // using CheckSchemeName() method
        bool value = Uri.CheckSchemeName(scheme);

        // Displaying the result
        if (value)
            Console.WriteLine("Scheme name is valid");
        else
            Console.WriteLine("Scheme name is invalid");
    }
}

Output:

Scheme name is valid

Example 2:

csharp

// C# program to demonstrate the
// Uri.CheckSchemeName(string) Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        // Declaring and initializing Uri
        Uri uri = new Uri("https://www.pierobon.org/iis/review1.htm.html#one");

        // Determining the Scheme of the Uri
        string scheme = uri.Scheme;

        // using CheckSchemeName() method
        bool value = Uri.CheckSchemeName(scheme);

        // Displaying the result
        if (value)
            Console.WriteLine("Scheme name is valid");
        else
            Console.WriteLine("Scheme name is invalid");
    }
}

Output:

Scheme name is valid
