C＃| Uri.CheckSchemeName(String)方法

Uri.CheckSchemeName(String)方法用于确定指定的方案名称是否有效。

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.

下面的程序说明了Uri.CheckSchemeName()方法的用法：

范例1：

// 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("http://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");
    }
}

输出：

Scheme name is valid

范例2：

// 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");
    }
}

输出：

Scheme name is valid
