[c#] Getting a POST variable

I am using C# with ASP.NET.

How do I check if a parameter has been received as a POST variable?

I need to do different actions if the parameter has been sent via POST or via GET.

In addition to using Request.Form and Request.QueryString and depending on your specific scenario, it may also be useful to check the Page's IsPostBack property.

if (Page.IsPostBack)
{
  // HTTP Post
}
else
{
  // HTTP Get
}

Use the

Request.Form[]

for POST variables,

Request.QueryString[]

for GET.
