any , advise appreciated

thank you

instead of using sqlcommand, try using sqlbulkcopy object.

something like...

datatable table = new datatable();     //turn csv data datatable using favorite csv parser.     //my favorite [`textfieldparser`][2].  using sqlbulkcopy copier = new sqlbulkcopy(connectionstring,                   sqlbulkcopyoptions.keepidentity or sqlbulkcopyoptions.keepnulls) {     // set column mappings via sqlbulkcopy.columnmappings     // choose destination table sqlbulkcopy.destinationtablename      // execute copy     copier.writetoserver(table); }
