我正在尝试填充 oracle 数据集 == NULL;
我将其与带有 C# 的 .NET Framework 2.0 一起使用
这是一个 system.data.oracleclient 示例http://msdn.microsoft.com/en-us/library/system.data.oracleclient.oracledataadapter%28v=vs.71%29.aspx(此示例是 1.1,但与 2.0 的工作方式相同)

OracleConnection conn = new OracleConnection("Data Source=Oracle8i;Integrated Security=yes");
Conn.Open;
OracleCommand cmd = conn.CreateCommand();
cmd.CommandText = "sp_pkg.getdata";
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new OracleParameter("a1", OracleType.Cursor)).Direction = ParameterDirection.Output;
cmd.Parameters.Add(new OracleParameter("a2", OracleType.Cursor)).Direction = ParameterDirection.Output;
DataSet ds = new DataSet();
OracleDataAdapter adapter = new OracleDataAdapter(cmd);
adapter.Fill(ds);
这是一个 ODP(推荐)示例:http://www.oracle.com/technology/sample_code/tech/windows/odpnet/DSPopulate/ViewProducts.cs.html

//Instantiate OracleDataAdapter to create DataSet
productsAdapter = new OracleDataAdapter();
//Fetch Product Details
productsAdapter.SelectCommand = new OracleCommand("SELECT " +
"Product_ID , " +
"Product_Name , " +
"Product_Desc , " +
"Category, " +
"Price " +
"FROM Products",conn);
//Instantiate DataSet object
productsDataSet = new DataSet("productsDataSet");
//Fill the DataSet with data from 'Products' database table
productsAdapter.Fill(productsDataSet, "Products");
//setting 'productsDataSet' as the datasouce and 'Products' table
//as the table to which the 'productsDataGrid' is Bound.
productsDataGrid.SetDataBinding(productsDataSet,"Products");
