I'm using C#/. I want to call a SQL stored procedure, pass parameters, and return a DataSet. Here's what I have so far:

SqlCommand oCommand = new SqlCommand("bm_GetProjects", oConn);
oCommand.CommandType = CommandType.StoredProcedure;

SqlParameter param1 = new SqlParameter();
param1.DbType = DbType.Int32;
param1.Direction = ParameterDirection.Input;
param1.ParameterName = "@AppKey";
param1.SourceColumn = "AppKey";
param1.SqlDbType = SqlDbType.Int;
param1.Value = 87;
oCommand.Parameters.Add(param1);


SqlParameter param2 = new SqlParameter();
param2.DbType = DbType.Int32;
param2.Direction = ParameterDirection.Input;
param2.ParameterName = "@CategoryTypeKey";
param2.SourceColumn = "CategoryTypeKey";
param2.SqlDbType = SqlDbType.Int;
param2.Value = 87;
oCommand.Parameters.Add(param2);



SqlParameter param3 = new SqlParameter();
param3.DbType = DbType.Int32;
param3.Direction = ParameterDirection.Input;
param3.ParameterName = "@ProjectStatusCodeKey";
param3.SourceColumn = "ProjectStatusCodeKey";
param3.SqlDbType = SqlDbType.Int;
param3.Value = 87;
oCommand.Parameters.Add(param3);


oDataSet = oCommand.;       // ***  WHAT GOES HERE??? ***

All the examples I found return a DataReader. How do I get back a data set?

Also, do I need to set all those properties on each parameter object?

Thanks
