我大约有20个文件,所有文件都超过20张。我需要将所有工作表中的特定数据导入表(与表相同的列)。我的代码只能导入一张纸。如何导入多张纸?以及如何从Excel导入特定的单元格?我读了很多问题,但是我什么都做不了,而且大多数都是旧的
数据库是SQL Server。我希望你能帮助我。我是新手。
public ActionResult Index()
{
return View();
}
[HttpPost]
public ActionResult Index(HttpPostedFileBase postedFile)
{
string filePath = string.Empty;
if (postedFile != null)
{
string path = Server.MapPath("~/Uploads/");
if (!Directory.Exists(path))
{
Directory.CreateDirectory(path);
}
filePath = path + Path.GetFileName(postedFile.FileName);
string extension = Path.GetExtension(postedFile.FileName);
postedFile.SaveAs(filePath);
string conString = string.Empty;
switch (extension)
{
case ".xls": //Excel 97-03.
conString = ConfigurationManager.ConnectionStrings["Excel03ConString"].ConnectionString;
break;
case ".xlsx": //Excel 07 and above.
conString = ConfigurationManager.ConnectionStrings["Excel07ConString"].ConnectionString;
break;
}
DataTable dt = new DataTable();
conString = string.Format(conString, filePath);
using (OleDbConnection connExcel = new OleDbConnection(conString))
{
using (OleDbCommand cmdExcel = new OleDbCommand())
{
using (OleDbDataAdapter odaExcel = new OleDbDataAdapter())
{
cmdExcel.Connection = connExcel;
//Get the name of First Sheet.
connExcel.Open();
DataTable dtExcelSchema;
dtExcelSchema = connExcel.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
string sheetName = dtExcelSchema.Rows[0]["TABLE_NAME"].ToString();
connExcel.Close();
//Read Data from First Sheet.
connExcel.Open();
cmdExcel.CommandText = "SELECT * From [" + sheetName + "]";
odaExcel.SelectCommand = cmdExcel;
odaExcel.Fill(dt);
connExcel.Close();
}
}
}
conString = ConfigurationManager.ConnectionStrings["Constring"].ConnectionString;
using (SqlConnection con = new SqlConnection(conString))
{
using (SqlBulkCopy sqlBulkCopy = new SqlBulkCopy(con))
{
//Set the database table name.
sqlBulkCopy.DestinationTableName = "dbo.Table_1";
//[OPTIONAL]: Map the Excel columns with that of the database table
sqlBulkCopy.ColumnMappings.Add("Rut", "Rut");
sqlBulkCopy.ColumnMappings.Add("Nombres", "Nombres");
sqlBulkCopy.ColumnMappings.Add("Malla", "Malla");
con.Open();
sqlBulkCopy.WriteToServer(dt);
con.Close();
}
}
}
return View();
}
}

我不知道您将如何使SQL Server做到这一点,而且如果您可以使C#做到这一点,可能会更加困难。我的意思是,您有这样的选择...
SELECT * INTO XLImport5 FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=C:\test\xltest.xls', 'SELECT * FROM [Customers$]')
这将从名为“ Customers”的工作表中导入所有内容(您需要在其中保留该$字符)。希望所有这些Excel文件之间都有某种一致的模式,但我只是在猜测。无论如何,如果我是您,我将通过下面的链接安装AddIn。遵循GIU并在Excel中聚合数据,因为在该环境中操作几乎可以肯定会容易得多。然后...将其从Excel发送到SQL Server。
