使用Sql连接字符串提取Excel数据

Question

My intention here is to render the excel data in a table, using a datatable, so opened an odbc connection and loaded the datatable like this:

System.Data.Odbc.OdbcConnection conn = new System.Data.Odbc.OdbcConnection(Dsn=Excel Files;Driver={Microsoft Excel Driver (*.xls)};Driverid=790;Dbq=C:\Users\*******\Documents\Book1.xlsx;DefaultDir=C:\Users\******\Documents;HDR=YES);
conn.Open();
DataTable dataTable = new DataTable();
string con = "select * from [sheet1$]";
System.Data.Odbc.OdbcCommand cmd = new System.Data.Odbc.OdbcCommand(con, conn);
System.Data.Odbc.OdbcDataReader dr = cmd.ExecuteReader();
dataTable.Load(dr);

But insted getting an error like this

ERROR [IM014] [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application

So actually whats' the root cause ?

Answer 1

Please use the following link as a possible solution to your problem:

ERROR [IM014] [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application

Answer 2

This suggests

"changing the Platform target project setting from Any CPU to x86."

will help. The root cause is, as the error says, a mismatch between the database driver and your application.

These docs say

If you use the 64-bit odbcad32.exe to configure or remove a DSN that connects to a 32-bit driver, for example, Driver do Microsoft Access (*.mdb), you will receive the following error message: The specified DSN contains an architecture mismatch between the Driver and Application To resolve this error, use the 32-bit odbcad32.exe to configure or remove the DSN.
