C# Read/Write into Access DB File
I want to write into Access Database File using C# Application, probably using WPF ... I also want the file to be password protected ... is it possible to connect to it while it is password protected开发者_JAVA技巧 or should I remove the password?
Use OleDbConnection (System.Data.OleDb) and the right connection string.
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\mydatabase.mdb;User Id=admin;Password=;
Our C# .Net4.0 Windows Forms data connection to MS Access looks like this:
using System.Data.OleDb;
...
private void DoIt()
{
OleDbConnection NamesDB = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=CyberSprocket.mdb");
try
{
NamesDB.Open();
}
catch (Exception ex) {
MessageBox.Show(ex.Message);
return;
}
OleDbCommand NamesCommand = new OleDbCommand("SELECT * FROM [names];", NamesDB);
OleDbDataReader dr = NamesCommand.ExecuteReader();
string theColumns = "";
for (int column = 0; column < dr.FieldCount; column++)
{
theColumns += dr.GetName(column) + " | ";
}
MessageBox.Show(theColumns);
NamesDB.Close();
}
Yes you can work with a password protected MS Access Database.
In your connection string to MS Access database, you can provide a USERNAME
and PASSWORD
.
Depending on which Security type is implemented, here are two samples:
Workgroup Security using a System Database
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\\Server\Share\MyData.mdb;Jet OLEDB:System Database=\\Server\Share\MyData.mdw;USER=userid, PWD=password"
With Standard MS Access Security:
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\\Server\Share\MyData.mdb;User ID=userid;Password=password;"
