How does ASP.net achieve page Jump?

During page development in ASP. NET, page Jump operations are often required. This is actually not difficult. The key is to know the problem. The operation method is provided below.

The Code is as follows:

[Html]
Protected void linkbutton#click (object sender, EventArgs e)
{
String url = "InfoShow. aspx ";
Response. Redirect (url );
}

Protected void linkbutton#click (object sender, EventArgs e)
{
String url = "InfoShow. aspx ";
Response. Redirect (url );
} Of course, we can pass parameters during page Jump. The Code is as follows:

[Html]
Protected void Menu1_MenuItemClick (object sender, MenuEventArgs e)
{
String url, s;
S = e. Item. Value. ToString ();
Url = "InfoRelease. aspx? UserName = "+ s. Trim ();
Response. Redirect (url );
}

Protected void Menu1_MenuItemClick (object sender, MenuEventArgs e)
{
String url, s;
S = e. Item. Value. ToString ();
Url = "InfoRelease. aspx? UserName = "+ s. Trim ();
Response. Redirect (url );
} The above is the code in one of my projects, so you can set items according to your own situation.

Now that the parameter is passed, how can we get it on the redirected page ???

The Code is as follows:

[Html]
Protected void Page_Load (object sender, EventArgs e)
{
If (Request ["UserName"]! = Null)
{
String s = Request ["UserName"]. ToString ();
// Form1.Visible = true;
TxtInfoclass. Text = s;
}
}

Protected void Page_Load (object sender, EventArgs e)
{
If (Request ["UserName"]! = Null)
{
String s = Request ["UserName"]. ToString ();
// Form1.Visible = true;
TxtInfoclass. Text = s;
}
}
Of course, there are several ways to pass the page parameters. You can refer to Baidu ......

[Html]
Protected void Page_Load (object sender, EventArgs e)
{
TxtAlert. Text = "";
If (Request ["UserName"]! = Null)
{
String s = Request ["UserName"]. ToString ();
// Form1.Visible = true;
TxtInfoclass. Text = s;
}
}

Protected void Page_Load (object sender, EventArgs e)
{
TxtAlert. Text = "";
If (Request ["UserName"]! = Null)
{
String s = Request ["UserName"]. ToString ();
// Form1.Visible = true;
TxtInfoclass. Text = s;
}
}
