所以,我正在做一个程序,它将一个excel文件导入到sql数据库,如果我指定excel的列和数据库列以及工作表名称,一切都可以正常工作。我将详细说明问题所在:
protected void Upload_Click(object sender, EventArgs e)
{
string excelPath = Server.MapPath("~/Nova pasta/") + Path.GetFileName(FileUpload1.PostedFile.FileName);
string filepath = Server.MapPath("~/Nova pasta/") + Path.GetFileName(FileUpload1.FileName);
string filename = Path.GetFileName(filepath);
FileUpload1.SaveAs(excelPath);
string ext = Path.GetExtension(filename);
String strConnection = @"Data Source=PEDRO-PC\SQLEXPRESS;Initial Catalog=costumizado;Persist Security Info=True;User ID=sa;Password=1234";
string excelConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + filepath + ";Extended Properties=\"Excel 12.0 Xml;HRD=YES;IMEX=1;\"";
OleDbConnection excelConnection = new OleDbConnection(excelConnectionString);
OleDbCommand cmd = new OleDbCommand("Select * from [rptListaMovs_4$]", excelConnection);
excelConnection.Open();
cmd.ExecuteNonQuery();
DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter("Select * from [rptListaMovs_4$] ", strConnection);
OleDbDataReader dReader;
dReader = cmd.ExecuteReader();
using (SqlBulkCopy sqlBulk = new SqlBulkCopy(strConnection))
{
sqlBulk.DestinationTableName = "Dados";
sqlBulk.ColumnMappings.Add("Data Mov", "Data Mov.");
sqlBulk.ColumnMappings.Add("Data Valor", "Data Valor");
sqlBulk.ColumnMappings.Add("Descrição do Movimento", "Descrição do Movimento");
sqlBulk.ColumnMappings.Add("Valor em EUR", "Valor em EUR");
sqlBulk.WriteToServer(dReader);
}
excelConnection.Close();
}
为此:"Select * from [rptListaMovs_4$]"
我想要这个:"Select * from ["+SheetNameWithoutCopyPastHisName+"]"
对此有兴趣
sqlBulk.ColumnMappings.Add("Data Mov", "Data Mov.");
sqlBulk.ColumnMappings.Add("Data Valor", "Data Valor");
sqlBulk.ColumnMappings.Add("Descrição do Movimento", "Descrição do Movimento");
sqlBulk.ColumnMappings.Add("Valor em EUR", "Valor em EUR");
我想要一些东西,不必放入列名,因为有时我想导入具有不同架构的excel,但不允许我这样做
答案 0 :(得分:2)
您应该可以使用以下方法获取工作表的第一名称:
DataTable schema = excelConnection.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
string sheetName = schema.Rows[0]["TABLE_NAME"].ToString();
对于字段名称,这应该可以解决问题:
for(int i = 0; i < dReader.FieldCount; i++)
{
sqlBulk.ColumnMappings.Add(dReader.GetName(i), dReader.GetName(i));
}
