Using SAS\Share and C#

Ok, I went a little crazy getting SAS\Share working with OleDb from C#. Since I got it figured out, someone else may have the same issue.

Here is how I did it. First of all, make sure you client machine and the SAS\Share server can talk to each other. I tested from a development machine that has SAS on it. Otherwise, a test app will have to be built.

In the web.config, I have these settings:

<add key=\"ShareConnectionString\" value=\"Provider=sas.ShareProvider.1;Data Source=share1;Location=192.168.1.199;User ID=Administrator;Password=<span color=\">*****</span>;Mode=ReadShare Deny None\"/>
<add key=\"SasLibrary\" value=\"demo\">
<add key=\"SasDataSet\" value=\"user_info\">

Here is the C# code:

private static DataTable LoadSasDataSet()
{
try
{
string library = ConfigurationManager.AppSettings["SasLibrary"] ;
string dataset = ConfigurationManager.AppSettings["SasDataSet"] ;
string conn = ConfigurationManager.AppSettings["ShareConnectionString"];

DataSet sasDs = new DataSet();
OleDbConnection sas = new OleDbConnection(conn);
sas.Open();

OleDbCommand sasCommand = sas.CreateCommand();
sasCommand.CommandType = CommandType.TableDirect;
sasCommand.CommandText = library + "." + dataset;

OleDbDataAdapter da = new OleDbDataAdapter(sasCommand);
da.Fill(sasDs);
sas.Close();

return sasDs.Tables[0];
}
catch (Exception ex)
{
Common.AddLogEntry("ERROR", "Unable to load SAS dataset", "", DateTime.Now, ex.ToString());
return null;
}
}

Keep in mind that there is also SQL capability within Share so that would be an option as well.
