Uri.IsLoopback属性是Uri类的属性,用于检查指定的Uri是否引用了本地主机。
句法:
public bool IsLoopback { get; }
返回值:该属性的返回类型为Boolean,如果此Uri引用本地主机,则返回true,否则返回false。
异常:如果此实例表示相对Uri,则此属性将提供InvalidOperationException,因为此属性仅适用于绝对URI。
范例1:
C#
// C# program to demonstrate the
// Uri.IsLoopback 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/");
// using IsLoopback property
bool status = v1.IsLoopback;
// checking the status
if (status)
Console.WriteLine("Given Uri is a reference of localhost");
else
Console.WriteLine("Given Uri is not reference of localhost");
}
}
C#
// C# program to demonstrate the
// Uri.IsLoopback property
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
// Declaring and initializing value1
Uri v1 = new Uri("http://localhost");
// using IsLoopback property
bool status = v1.IsLoopback;
// checking the status
if (status)
Console.WriteLine("Given Uri is a reference of localhost");
else
Console.WriteLine("Given Uri is not reference of localhost");
}
}
输出:
Given Uri is not reference of localhost
