基本思路:
1 Session源网站设置Session数据同时,把SessionID和Session数据一起插入一个数据库中,再把SessionID作为查询字符串传递到Session获取网站.
2 Session获取网站从数据库中按SessionID查询获取Session数据并赋值到本网站的Session中.
示例:
Session源网站部分:
private
void
Button1_Click(
object
sender, System.EventArgs e)
{
try
{ this.TextBox1.Text = Session.SessionID; Session["Name"] = this.TextBox2.Text; Session["Role"] = this.TextBox3.Text; OleDbConnection conn = new OleDbConnection( @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\webTest.mdb;Persist Security Info=False" ); string strInsertSql = "insert into SessionData " + " ( SessionID, SessionName, SessionRole ) " + " values " + "( '" + Session.SessionID + "', '" + Session["Name"] + "', '" + Session["Role"] + "' )"; conn.Open(); OleDbCommand cmd = new OleDbCommand( strInsertSql, conn ); cmd.ExecuteNonQuery(); conn.Close(); this.TextBox1.Text = "Session保存成功"; string strJumpUrl = "http://localhost/SessionReadFromOtherSite/ReadOtherSession.aspx?SessionId=" + Session.SessionID; Response.Write("<script>window.open('" + strJumpUrl + "');</script>"); 
} catch( System.Exception ex ) { this.TextBox1.Text = ex.Message; } 
}
Session获取网站部分:
private
void
Page_Load(
object
sender, System.EventArgs e)
{ try { if ( Request.QueryString["SessionID"] != null ) { OleDbConnection conn = new OleDbConnection( @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\webTest.mdb;Persist Security Info=False" ); string strSql = "select " + " SessionID, SessionName, SessionRole " + " from SessionData " + " where SessionID = '" + Request.QueryString["SessionID"].ToString() + "'"; OleDbDataAdapter da = new OleDbDataAdapter( strSql, conn ); DataSet ds = new DataSet(); da.Fill( ds ); Session["Name"] = ds.Tables[0].Rows[0]["SessionName"].ToString(); Session["Role"] = ds.Tables[0].Rows[0]["SessionRole"].ToString(); this.TextBox1.Text = ds.Tables[0].Rows[0]["SessionID"].ToString(); this.TextBox2.Text = Session["Name"].ToString(); this.TextBox3.Text = Session["Role"].ToString(); } } catch( System.Exception ex ) { this.TextBox1.Text = ex.Message; } }
