Question

Does anyone know how to write to an excel file (.xls) via OLEDB in C#? I’m doing the following:

   OleDbCommand dbCmd = new OleDbCommand('CREATE TABLE [test$] (...)', connection);    dbCmd.CommandTimeout = mTimeout;    results = dbCmd.ExecuteNonQuery(); 

But I get an OleDbException thrown with message:

‘Cannot modify the design of table ‘test$’. It is in a read-only database.’

My connection seems fine and I can select data fine but I can’t seem to insert data into the excel file, does anyone know how I get read/write access to the excel file via OLEDB?

Answer 1

You need to add ReadOnly=False; to your connection string

Provider=Microsoft.Jet.OLEDB.4.0;Data Source=fifa_ng_db.xls;Mode=ReadWrite;ReadOnly=false;Extended Properties=\'Excel 8.0;HDR=Yes;IMEX=1\';
