Question

I have an array containing a list of file paths that I want to insert into an SQL database.

string[] filePaths = Directory.GetFiles(@"C:\Test Folder");

I am confident in setting up and connecting to the database, I just can’t figure out how to take each element and place it in a new row in the database.

Thanks,
Matt

Answer 1

It depends on which technology you are using (Please note that when inserting lots of rows the use of SqlBulkCopy is recommended).

ADO.NET

foreach (var path in filePaths)
{
   var command = new SqlCommand("INSERT INTO mytable(col1) VALUES(@param1)", connection);
   command.Parameters.AddWithValue("@param1", path);
   command.ExecuteNonQuery();
}

LINQ-to-SQL

var projection = filePaths.Select(a => new MyTable() { Col1 = a });
myContext.InsertAllOnSubmit(projection);
myContext.SubmitChanges();

LINQ-to-Entities

foreach (var path in filePaths)
{
   myModel.MyTable.AddObject(new MyTable() { Col1 = path });
}
myModel.SaveChanges();
