我正在上传一个有 5 张工作表的 Excel。上传时出现错误“定义的字段过多”
public DataSet ExportQCCheckData(string filepath)
{
string path = filepath;
OleDbConnection con;
System.Data.DataTable dt = null;
//Connection string for oledb
string conn = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" + path + "; Extended Properties='Excel 8.0;IMEX=1;'";
con = new OleDbConnection(conn);
try
{
con.Open();
//get the sheet name in to a table
dt = con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
String[] excelsheets = new String[dt.Rows.Count];
int i = 0;
//using foreach get the sheet name in a string array called excelsheets[]
foreach (DataRow dr in dt.Rows)
{
excelsheets[i] = dr["TABLE_NAME"].ToString();
i++;
}
DataSet ds = new DataSet();
int cnt = 0;
foreach (string temp in excelsheets)
{
if (temp == "BASIC$" || temp == "SHORT$" || temp == "CLASS$" || temp == "MEMO$" || temp == "SOURCE$")
{
string query = "select * from [" + temp + "]";
OleDbDataAdapter adp = new OleDbDataAdapter(query, con);
adp.Fill(ds, temp);
cnt++;
}
}
if (cnt != 5)
{
ds = null;
}
return ds;
}
catch (Exception ex)
{
Console.Write(ex.Message);
DataSet ds = null;
return ds;
}
finally
{
con.Close();
}
}
