只求一个简单的进度条实现，能帮我结解问题我就把分全给他~~急。

Question

 private void ButShow_Click_1(object sender, EventArgs e)
        {
            
            if(DBF.Text!="" &&  Access.Text!="")
            {
                if(CheckComm.Checked==true)
                {
                    int Count = 0;
                    DataTable A_dt = Access_Bing();
                    for (int i = 0; i < A_dt.Rows.Count; i++)
                    {
                        int M_Id = Convert.ToInt32(A_dt.Rows[i]["M_Id"]);//Access库Meter的主键
                        string str = A_dt.Rows[i]["Meter_ID"].ToString();//Access库Meter的通讯地址
                        if(str.Length>5)
                        {
                            DataTable D_dt = Dbf_Bing(str);
                            if (D_dt.Rows.Count != 0)
                            {
                                string Cid = D_dt.Rows[0]["Cid"].ToString();//用户编号
                                string Caddr = D_dt.Rows[0]["Caddr"].ToString();//表安装地址
                                string Rid = D_dt.Rows[0]["Rid"].ToString();//表资产编号
                                Access_Update(Cid, Caddr, Rid, M_Id);
                                Count++;
                            }
                        }
                    }
                    MessageBox.Show("已成功导入"+Count.ToString()+"条数据!", "系统提示......");
                    A_Bing();
                }
            }
            else
            {
                MessageBox.Show("dbf文件或mdb文件为空，请正确的选择文件！");
            }
        }这是button事件里的代码。就是从dbf库里读数据,再放入到access里面。数据多有点慢， 代码没问题，我就只想加一个进度条。但是要和我这个程序相符的。 进度条控件名：Pb  timer控件名：timer1  我不想用线程，所以最简单的行。

Answer 2

Pb.Maxmum=A_dt.Rows.Count;
Pb.Value=0;
for (int i = 0; i < A_dt.Rows.Count; i++)
                    {
                        int M_Id = Convert.ToInt32(A_dt.Rows[i]["M_Id"]);//Access库Meter的主键
                        string str = A_dt.Rows[i]["Meter_ID"].ToString();//Access库Meter的通讯地址
                        if(str.Length>5)
                        {
                            DataTable D_dt = Dbf_Bing(str);
                            if (D_dt.Rows.Count != 0)
                            {
                                string Cid = D_dt.Rows[0]["Cid"].ToString();//用户编号
                                string Caddr = D_dt.Rows[0]["Caddr"].ToString();//表安装地址
                                string Rid = D_dt.Rows[0]["Rid"].ToString();//表资产编号
                                Access_Update(Cid, Caddr, Rid, M_Id);
                                Count++;
                            }
                        }
                    }
                    MessageBox.Show("已成功导入"+Count.ToString()+"条数据!", "系统提示......");
                    A_Bing();
Pb.Value+=1;
                }

Answer 3

Pb.Value+=1;放错地方了，要放循环里
后面再要加一句Application.DoEvents();

Answer 4

for (int i = 0; i < A_dt.Rows.Count; i++)
                    {
ProgressBar1.Value = i * 100 / A_dt.Rows.Count;//加这一句，在from里加控件ProgressBar
