使用c#判断网络连接状态的代码。
代码:
public partial class Form1 : Form {
[DllImport("wininet.dll")]
private extern static bool getInterState(out int conn, int val);
public Form1() {
InitializeComponent();
getNet();
}
//判断当前是否连接入Internet网络
private void getNet()
{ www.jbxue.com
int Out;
if (getInterState(out Out, 0) == true)
{
label1.Text = " 网络已连接!";
}else{
label1.Text = " 网络未成功连接!";
}
}
}
[DllImport("wininet.dll")]
private extern static bool getInterState(out int conn, int val);
public Form1() {
InitializeComponent();
getNet();
}
//判断当前是否连接入Internet网络
private void getNet()
{ www.jbxue.com
int Out;
if (getInterState(out Out, 0) == true)
{
label1.Text = " 网络已连接!";
}else{
label1.Text = " 网络未成功连接!";
}
}
}
