C# | Uri。CheckSchemeName(字符串)方法

原文:https://www . geesforgeks . org/c-sharp-uri-checkschemnamestring-method/

乌利。CheckSchemeName(String)方法用于判断指定的方案名称是否有效。

语法:公共静态 bool CheckSchemeName(字符串 scheme name)； 这里需要方案名进行验证。

返回值:如果方案名称有效，则该方法返回布尔值 true ，否则返回 false。

下面的程序说明了 Uri 的使用。CheckSchemeName() 方法:

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("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

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");
    }
}

Output:

Scheme name is valid
