at class declaration :
public partial class EndUser_FS_File_History : System.Web.UI.Page
{
ReportDocument reportdocument = null;
..........
at load crystal report:
reportdocument = new ReportDocument();
string connectionString = ConfigurationManager.ConnectionStrings["FileSystemConnectionString"].ConnectionString;
SqlConnectionStringBuilder SConn = new SqlConnectionStringBuilder(connectionString);
reportdocument.Load(Server.MapPath(#"~/Admin/UserReport.rpt"));
reportdocument.SetDataSource(myDataSet);
reportdocument.DataSourceConnections[0].SetConnection(SConn.DataSource, SConn.InitialCatalog, SConn.UserID, SConn.Password);
CrystalReportViewer1.ReportSource = reportdocument;
and at Page_Unload event:
protected void Page_Unload(object sender, EventArgs e)
{
if (reportdocument != null)
{
reportdocument.Close();
reportdocument.Dispose();
}
GC.Collect();
}

There are few steps:
Before Pageload, declare the report as
ReportDocument rpt = null;
protected void Page_Load(object sender, EventArgs e)
{
try
{
rpt= new ReportName; //this is the name of your report
// do all the logic here
}
catch()
{
}
}
protected void Page_Unload(object sender, EventArgs e)
{
if(rpt!=null)
{
rpt.Close();
rpt.Dispose();
}
GC.Collect();
}
