C#中关于数据库中插入数据的

private SqlCommand GetInsertCommand()
    {
        string str = "server=.;database=student;uid=sa;pwd=;";

        SqlConnection myconn = new SqlConnection(str);
        SqlCommand mycomm = new SqlCommand("InsertStudent", myconn);

        mycomm.CommandType = CommandType.StoredProcedure;

        SqlParameterCollection sqlpara = mycomm.Parameters;
        sqlpara.Add("@sno", SqlDbType.Int);
        sqlpara.Add("@sname", SqlDbType.VarChar);
        sqlpara.Add("@s易做图", SqlDbType.Bit);
        sqlpara["@sno"].SourceColumn = "sno";
        sqlpara["@sname"].SourceColumn = "sname";
        sqlpara["@s易做图"].SourceColumn = "s易做图";

        return mycomm;
    }

    protected void Button1_Click(object sender, EventArgs e)
    {

        DataSet myset = new DataSet();
        DataTable mytable = new DataTable();
        mytable.Columns.Add("sno", typeof(Int32));
        mytable.Columns.Add("sname", typeof(String));
        mytable.Columns.Add("s易做图", typeof(Boolean));
        DataRow myrow = mytable.NewRow();
        myrow[0] = Convert.ToInt32(NoBox.Text);
        myrow[1] = NameBox.Text;
        if (RadioButton1.Checked)
            myrow[2] = 1;
        else myrow[2] = 0;
        mytable.Rows.Add(myrow);
        myset.Tables.Add(mytable);


        SqlDataAdapter myadapter = new SqlDataAdapter();

        myadapter.InsertCommand = GetInsertCommand();

        try
        {
            myadapter.Update(myset,"student");
            Label4.Visible = true;
            Label4.Text = "数据添加成功";
        }
        catch (Exception ee)
        {
            Response.Write(ee.Message);
            Label4.Visible = true;
            Label4.Text = "插入失败";
        }
    }
}
Update 无法找到 TableMapping['student'] 或 DataTable“student”。怎么回事啊？谢谢
--------------------编程问答-------------------- DataTable mytable = new DataTable();
改为
DataTable mytable = new DataTable("student");

引用 1 楼 fangxinggood 的回复:

DataTable mytable = new DataTable();
改为
DataTable mytable = new DataTable("student");

应该就是这个问题 --------------------编程问答-------------------- DataTable mytable = new DataTable("student");
myadapter.Update(mytable );
