这个界面很简单,代码就不列出来了。
二、导入的代码
我分了两部分,第一部分是点击查看数据的代码,这个是将数据导入到DataTable里面,但是还没有导入到数据库里。这里需要注意的是当程序在服务器运行时,要先把导入的文件上传到服务器上,否则不能导入,会出现莫名奇妙的错误,为了改这个错误当初弄了好久,希望大家不要走我的弯路啊。如果是在自己的机器上就不用上穿文件。
第二部分是选择相应的表,然后将数据导入到表里面,这部分很简单。
1、
try
{
InputDataBLL input = new InputDataBLL();
this.Label1.Text = "";
if (this.FileUpload1.HasFile)
{
// string filename = this.FileUpload1.PostedFile.FileName.ToString().Trim();
DataTable inputdt = new DataTable();
int len = this.FileUpload1.FileName.ToString().Trim().Length;
string path = "~/temp/upfile/"+this.FileUpload1 .FileName .ToString ().Trim();
path = Server.MapPath(path);
this.FileUpload1.SaveAs(path); //上传文件
inputdt = input.InputExcel(path, this.FileUpload1.FileName.ToString().Trim().Substring(0, len - 4),this.TextBox1.Text.Trim ());
if (Session["inputdt"] != null)
Session.Remove("inputdt");
Session.Add("inputdt", inputdt);
if (inputdt.Rows.Count > 0)
{
this.GridView1.DataSource = inputdt;
this.GridView1.DataBind();
}
}
else
throw new Exception("请选择导入表的路径");
}
catch (Exception ex)
{
Response.Write("<script language='javascript'>alert('" + ex.Message + "');</script>");
}
{
InputDataBLL input = new InputDataBLL();
this.Label1.Text = "";
if (this.FileUpload1.HasFile)
{
// string filename = this.FileUpload1.PostedFile.FileName.ToString().Trim();
DataTable inputdt = new DataTable();
int len = this.FileUpload1.FileName.ToString().Trim().Length;
string path = "~/temp/upfile/"+this.FileUpload1 .FileName .ToString ().Trim();
path = Server.MapPath(path);
this.FileUpload1.SaveAs(path); //上传文件
inputdt = input.InputExcel(path, this.FileUpload1.FileName.ToString().Trim().Substring(0, len - 4),this.TextBox1.Text.Trim ());
if (Session["inputdt"] != null)
Session.Remove("inputdt");
Session.Add("inputdt", inputdt);
if (inputdt.Rows.Count > 0)
{
this.GridView1.DataSource = inputdt;
this.GridView1.DataBind();
}
}
else
throw new Exception("请选择导入表的路径");
}
catch (Exception ex)
{
Response.Write("<script language='javascript'>alert('" + ex.Message + "');</script>");
}
导入的函数
/// <summary>
/// 导入数据到数据集中
/// </summary>
/// <param name="Path"></param>
/// <param name="TableName"></param>
/// <param name="tablename2">如果这个有就以他为表名,没有的话就以TableName</param>
/// <returns></returns>
public DataTable InputExcel(string Path,string TableName,string tablename2)
{
try
{
string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + Path + ";" + "Extended Properties=Excel 8.0;";
OleDbConnection conn = new OleDbConnection(strConn);
conn.Open();
string strExcel = "";
OleDbDataAdapter myCommand = null;
if (tablename2.Length > 0 && !tablename2.Equals(string.Empty))
TableName = tablename2;
strExcel = "select * from [" + TableName + "$]";
myCommand = new OleDbDataAdapter(strExcel, strConn);
DataTable dt = new DataTable();
myCommand.Fill(dt);
conn.Close();
return dt;
}
catch (Exception ex)
{
throw new Exception(ex.Message);
}
}
二、将数据导入到数据库里/// 导入数据到数据集中
/// </summary>
/// <param name="Path"></param>
/// <param name="TableName"></param>
/// <param name="tablename2">如果这个有就以他为表名,没有的话就以TableName</param>
/// <returns></returns>
public DataTable InputExcel(string Path,string TableName,string tablename2)
{
try
{
string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + Path + ";" + "Extended Properties=Excel 8.0;";
OleDbConnection conn = new OleDbConnection(strConn);
conn.Open();
string strExcel = "";
OleDbDataAdapter myCommand = null;
if (tablename2.Length > 0 && !tablename2.Equals(string.Empty))
TableName = tablename2;
strExcel = "select * from [" + TableName + "$]";
myCommand = new OleDbDataAdapter(strExcel, strConn);
DataTable dt = new DataTable();
myCommand.Fill(dt);
conn.Close();
return dt;
}
catch (Exception ex)
{
throw new Exception(ex.Message);
}
}
这部分其实很简单,就是插入数据。
if (this.DropDownList1.SelectedItem.Text.ToString().Equals("Material"))//导物料
{
new StockBaseBLL().ISUserModel("物料导入", Response, Request, Server);
MaterialBLL material = new MaterialBLL();
foreach (DataRow row in inputdt.Rows)//inputdt为刚刚从函数中返回的数据源
{
float MaterialPrice = 0.0f;
float MaterialTaxPrice = 0.0f;
float TaxRate = 0.0f;
float Moneys = 0.0f;
int temp=0;
if (row["单价"].ToString().Trim() != "")
MaterialPrice = float.Parse(row["单价"].ToString().Trim());
if (row["含税单价"].ToString().Trim()!="")
MaterialTaxPrice=float.Parse(row["含税单价"].ToString().Trim());
if (row["税率"].ToString().Trim()!="")
TaxRate= float.Parse(row["税率"].ToString().Trim());
if (row["金额"].ToString().Trim()!="")
Moneys=float.Parse(row["金额"].ToString().Trim());
if (material.SelectMaterialsDynamic("MaterialID='" + row["物料长代码"].ToString() + "'", "").Rows.Count <= 0) //不存在,其实可以不要,因为编号是主键,如果相同则插不进去
temp = material.InsertMaterial(row["物料长代码"].ToString(), row["物料名称"].ToString(), row["单位"].ToString().Trim(), MaterialPrice, MaterialTaxPrice, TaxRate, Moneys, 0);
else
NotIntoID += row["物料长代码"].ToString()+",";
if (temp > 0)
index += temp;
temp = 0;
}
}
{
new StockBaseBLL().ISUserModel("物料导入", Response, Request, Server);
MaterialBLL material = new MaterialBLL();
foreach (DataRow row in inputdt.Rows)//inputdt为刚刚从函数中返回的数据源
{
float MaterialPrice = 0.0f;
float MaterialTaxPrice = 0.0f;
float TaxRate = 0.0f;
float Moneys = 0.0f;
int temp=0;
if (row["单价"].ToString().Trim() != "")
MaterialPrice = float.Parse(row["单价"].ToString().Trim());
if (row["含税单价"].ToString().Trim()!="")
MaterialTaxPrice=float.Parse(row["含税单价"].ToString().Trim());
if (row["税率"].ToString().Trim()!="")
TaxRate= float.Parse(row["税率"].ToString().Trim());
if (row["金额"].ToString().Trim()!="")
Moneys=float.Parse(row["金额"].ToString().Trim());
if (material.SelectMaterialsDynamic("MaterialID='" + row["物料长代码"].ToString() + "'", "").Rows.Count <= 0) //不存在,其实可以不要,因为编号是主键,如果相同则插不进去
temp = material.InsertMaterial(row["物料长代码"].ToString(), row["物料名称"].ToString(), row["单位"].ToString().Trim(), MaterialPrice, MaterialTaxPrice, TaxRate, Moneys, 0);
else
NotIntoID += row["物料长代码"].ToString()+",";
if (temp > 0)
index += temp;
temp = 0;
}
