Examples

The following code example creates a SessionStateItemCollection collection from a file that was created using the Serialize method.

System.IO.BinaryReader reader = new System.IO.BinaryReader(
  System.IO.File.Open(Server.MapPath("session_collection.bin"), System.IO.FileMode.Open));

SessionStateItemCollection sessionItems = SessionStateItemCollection.Deserialize(reader);

for (int i = 0; i < sessionItems.Count; i++)
  Response.Write("sessionItems[" + i + "] = " + sessionItems[i].ToString() + "<br />");

Dim reader As System.IO.BinaryReader = New System.IO.BinaryReader( _
  System.IO.File.Open(Server.MapPath("session_collection.bin"), System.IO.FileMode.Open))

Dim sessionItems As SessionStateItemCollection = SessionStateItemCollection.Deserialize(reader)

For I As Integer = 0 To sessionItems.Count - 1
  Response.Write("sessionItems(" & i & ") = " & sessionItems(i).ToString() & "<br />")
