您是否在每个会话中都创建DataTable的新实例?

如果为true，为什么要在DataTable中使用静态成员?我认为您正在为每个用户使用相同的数据表.

尝试创建一个新的DataTable实例并禁用静态成员，它可以解决问题.

在此示例中，我更改了DataTable类的名称，因为它与原始DataTable相同.

例如:

Are you creating a new instance of DataTable in every session?

If true, why you''re using the static member in DataTable? I think that you''re using the same datatable for every user.

Try to create a new instance of DataTable and disable the static member, It can solve the problem.

For this example, I changed the name of DataTable class, because it''s the same that the original DataTable.

Ex:

//Classpublic
class MyDataTable
{
    public DataTable dt;
    public DataTable()
    {
        dt = new DataTable();
        dt.Columns.Add("Col1");
        dtColumns.Add("Col2");
    }
}

//Web-Page
protected void btSave_Click()
{   //Code to add data to datatable.
    MyDataTable dt = new MyDataTable();
    MyDataTable.dt.Rows.Add(DataRows);
    Session["DataTable"] = MyDataTable.dt;
    //  saving dataTable to session.
    Grid.DataSource = (DataTable)Session["DataTable"];
}

是的，您删除了

yes, you remove the

public static  DataTable  dt

到

to

public DataTable dt
