Uri.DnsSafeHost属性是实例属性,用于获取未转义的主机名,该主机名可以安全地用于DNS解析。
句法 :
public string DnsSafeHost { get; }
返回值:该属性返回字符串 ,它以适合DNS解析的格式返回URI的主机部分,如果已经适合解析,则返回原始主机字符串。
异常:如果实例是相对URI,并且此属性仅对绝对URI有效,则此属性将提供InvalidOperationException 。
范例1:
C#
// C# program to demonstrate the
// Uri.DnsSafeHost property
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main() {
// Declaring and initializing value1
Uri v1 = new Uri("https://www.geeksforgeeks.org/greedy-algorithms/#standardGreedyAlgorithms");
// using DnsSafeHost property
Console.WriteLine("Uri DnsSafeHost: " + v1.DnsSafeHost);
}
}
C#
// C# program to demonstrate the
// Uri.DnsSafeHost property
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
// Declaring and initializing value1
Uri v1 = new Uri("https://docs.microsoft.com/en-us/dotnet/api/system.uri.isloopback?view=netcore-3.1");
// using DnsSafeHost property
Console.WriteLine("Hostname: "+ v1.DnsSafeHost);
}
}
输出:
Hostname: www.geeksforgeeks.org
