1.导入数据思路：
C#winform程序中，要导入数据，给一个EXCEL模板，让用户按照给的模板填好数据，然后在程序中一条一条的进行导入数据。
比如
foreach (DataRow dr in dt.Rows)
{
//校区
XX0103BLL bll_xx0103 = new XX0103BLL();
XX0103Model.Base model_xx0103 = new XX0103Model.Base();
if (bll_xx0103.Exists("", dr["校区编号"].ToString(), dr["校区名称"].ToString()) == false)
{
//没有校区添加校区
model_xx0103.XQBH = dr["校区编号"].ToString();
model_xx0103.XQMC = dr["校区名称"].ToString();
bll_xx0103.Add(model_xx0103);
}
}
注意：这里要判段每一条数据是否符合规范，符合的才往数据库里面插入数据。不符合的就continue。
2.进度条
2.1导入按钮的单击事件
/// <summary>
/// 导入数据
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void btn_Import_Click(object sender, EventArgs e)
{
ProcessThread = new Thread(new ThreadStart(LoadBasicData));
ProcessThread.IsBackground = true;
ProcessThread.Start();
}
2.2 LoadBasicData方法
/// <summary>
/// 基础数据导入
/// </summary>
private void LoadBasicData()
{
this.NowCount = 0;
this.AllCount = 0;
this.hasResult = false;
try
{
DelegateShowProssBar mi = new DelegateShowProssBar(ShowProcessBar);
this.BeginInvoke(mi, new object[] { "导入基础数据", "导入数据", true });
Thread.Sleep(1000);//等待进度条弹出
object[] objPar = new object[] { 0, "导入数据...\r" };
object objReturn;
this.Invoke(this.myIncrease, objPar);
this.AllCount = dt.Rows.Count;
this.wpf.SetMaxValue(this.AllCount);
objPar = new object[] { this.NowCount, "开始导入数据...\r" };
this.Invoke(this.myIncrease, objPar);
foreach (DataRow dr in dt.Rows)
{
this.NowCount++;
//校区
XX0103BLL bll_xx0103 = new XX0103BLL();
XX0103Model.Base model_xx0103 = new XX0103Model.Base();
if (bll_xx0103.Exists("", dr["校区编号"].ToString(), dr["校区名称"].ToString()) == false)
{
//没有校区添加校区
model_xx0103.XQBH = dr["校区编号"].ToString();
model_xx0103.XQMC = dr["校区名称"].ToString();
bll_xx0103.Add(model_xx0103);
}
//部门
XX0301BLL bll_xx0301 = new XX0301BLL();
XX0301Model.Base model_xx0301 = new XX0301Model.Base();
if (bll_xx0301.Exists("", dr["校区编号"].ToString(), dr["部门编号"].ToString(), dr["部门名称"].ToString()) == false)
{
model_xx0301.BMBH = dr["部门编号"].ToString();
model_xx0301.BMMC = dr["部门名称"].ToString();
model_xx0301.XQBH = dr["校区编号"].ToString();
bll_xx0301.Add(model_xx0301);
}
//专业
JX01BLL bll_jx01 = new JX01BLL();
JX01Model.Base model_jx01 = new JX01Model.Base();
if (bll_jx01.Exists("", dr["专业编号"].ToString()) == false)
{
model_jx01.ZYBH = dr["专业编号"].ToString();
model_jx01.ZYMC = dr["专业名称"].ToString();
model_jx01.BMBH = dr["部门编号"].ToString();
model_jx01.CC = dr["层次"].ToString();
bll_jx01.Add(model_jx01);
}
//用户
CustomerBLL bll_customer = new CustomerBLL();
CustomerModel.Base model_customer = new CustomerModel.Base();
if (bll_customer.Exists("", dr["考生号"].ToString()) == false)
{
model_customer.OutID = dr["考生号"].ToString();
model_customer.CardNo = int.Parse(dr["卡号"].ToString());
model_customer.Name = dr["姓名"].ToString();
model_customer.CardSN = int.Parse(dr["换卡序号"].ToString());
model_customer.Sex = dr["性别"].ToString();
model_customer.CustomerTypeID = int.Parse(dr["客户类别"].ToString());
model_customer.NJ = dr["年级"].ToString();
model_customer.ZYBH = dr["专业编号"].ToString();
model_customer.CardStatusID = int.Parse(dr["卡状态码"].ToString());
model_customer.IDCardNo = dr["身份证号"].ToString();
model_customer.CardTypeID = int.Parse(dr["卡类别码"].ToString());
model_customer.AddTime = DateTime.Now;
bll_customer.Add(model_customer);
}
if (!this.hasResult)
{
objPar = new object[] { this.NowCount, "" };
objReturn = this.Invoke(this.myIncrease, objPar);
hasResult = ((WaitProcessFormEx.ResStruct)objReturn).HasResult;
bool canceled = ((WaitProcessFormEx.ResStruct)objReturn).Canceled;
if (hasResult)
{
if (this.NowCount == this.AllCount)
{
// showResult(true, "完成! ");
}
else
{
showResult(false, canceled ? "操作被取消! " : "导入未完成! ");
return;
}
}
}
else
{
}
}
objPar = new object[] { this.NowCount, "数据导入完成！" };
this.Invoke(this.myIncrease, objPar);
}
catch
{
Error("错误", "数据导入错误");
}
}
3.提供一个读EXCEL，转DataTable的方法，注意：只能是excel2003或者excel2007的EXCEL表
/// <summary>
/// 读excel
/// </summary>
/// <param name="fileFullPath">excel路径</param>
/// <returns></returns>
public DataTable ReadExcel(string fileFullPath)
{
OleDbConnection myConn = null;
OleDbDataAdapter myCommand = null;
DataSet dst = null;
string StrCon = "";
if (fileFullPath.Substring(fileFullPath.LastIndexOf(".")).ToLower() == ".xls")
{
StrCon = "Provider = Microsoft.Jet.OLEDB.4.0;Data Source=" + fileFullPath +
";Extended Properties=‘Excel 8.0;HDR=Yes;IMEX=1‘";
}
else if (fileFullPath.Substring(fileFullPath.LastIndexOf(".")).ToLower() == ".xlsx")
{
StrCon = "Provider =Microsoft.ACE.OLEDB.12.0;Data Source=" + fileFullPath +
";Extended Properties=‘Excel 12.0;HDR=Yes;IMEX=1‘";
}
else if (fileFullPath.Substring(fileFullPath.LastIndexOf(".")).ToLower() == ".mdb")
{
StrCon = " Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" + fileFullPath + "; User Id=; Password=";
}
else
{
this.Error("错误", "文件格式不正确");
}
myConn = new OleDbConnection(StrCon);
myConn.Open();//打开Excel连接
//查询excel文件中有多少张表
DataTable dt = myConn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);//查询所有表
if (dt.Rows.Count == 0)
{
this.Error("错误", "文件中没有可用的表");
}
string sql = "select * from [{0}]";
bool flag = false;
foreach (DataRow d in dt.Rows)//列出所有表以供选择
{
if (d["TABLE_TYPE"].ToString().ToUpper() == "TABLE")
{
//sql += d[2].ToString().Replace("‘", "");
sql = string.Format(sql, d[2].ToString().Replace("‘", ""));
flag = true;
break;
}
}
if (flag == false)
{
this.Error("错误", "没有可用的表");
}
myCommand = new OleDbDataAdapter(sql, myConn);
dst = new DataSet();
myCommand.Fill(dst);
return dst.Tables[0];
}
