Windows窗体应用程序-IP统计信息 [英] Windows Form Application - IP Statistics

问题描述

为什么会出现此错误?
方法"ShowIPStatistics"的无重载采用"0"参数"
我知道它必须有一些参数，但是当我传递参数(NetworkInterfaceComponent)时，它会传递另一条错误消息.

Why I got this error?
"No overload for method ''ShowIPStatistics'' takes ''0'' arguments"
I know it must have some arguments, but when I pass the argument (NetworkInterfaceComponent), it delivers another err message.

using System.Net.NetworkInformation;
namespace WindowsFormsApplication4
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        private void Form1_Load(object sender, EventArgs e)
        {
        }
        public static void ShowIPStatistics(NetworkInterfaceComponent version) 
        {
            //code for showing IP statistics
        }
        private void button1_Click(object sender, EventArgs e)
        {
            ShowIPStatistics();
        }
    }
}

推荐答案

错误消息说明了所有这些，您必须传递一个参数，因为您已定义了必须将NetworkInterfaceComponent传递给该方法. br/>

The error message says it all, you have to deliver a parameter, since you have defined that NetworkInterfaceComponent must be passed to the method.

private void button1_Click(object sender, EventArgs e)
{
    ShowIPStatistics(); //<-- this is causing the problem
}

[添加]
如果您使用的是Visual Studio，请双击错误将您带到问题所在的地方.

[Addition]
If you''re using Visual Studio, double clicking the error takes you to the place where the problem is.

好吧，因为您在没有任何调用的情况下调用了ShowIPStatistics()参数.

Well you are getting it because you make a call to ShowIPStatistics() without any parameters.

private void button1_Click(object sender, EventArgs e)
{
    ShowIPStatistics();  // <<<<<============= HERE ======================
}

您必须传递NetworkInterfaceComponent.这是您的方法，您应该知道！

You have to pass in a NetworkInterfaceComponent. It''s your method, you should know that!

NetworkInterfaceComponent是一个枚举.它有两个可能的值IPv4或IPv6.

因此，您必须使用以下任一方法:

The NetworkInterfaceComponent is an enumeration. It has two possible values IPv4 or IPv6.

Therefore you have to use either:

private void button1_Click(object sender, EventArgs e)
{
    ShowIPStatistics(NetworkInterfaceComponent.IPv4);
}

或:

or:

private void button1_Click(object sender, EventArgs e)
{
    ShowIPStatistics(NetworkInterfaceComponent.IPv6);
}
