请访问 oracle 为 Microsoft OracleClient Developers 设置的这个 ODP 站点:http://www.oracle.com/technetwork/topics/dotnet/index-085703.html

下面还有一个示例代码，可以让您开始从 C# 到 Oracle 调用存储过程.PKG_COLLECTION.CSP_COLLECTION_HDR_SELECT 是建立在 Oracle 之上的存储过程，接受参数 PUNIT、POFFICE、PRECEIPT_NBR 并在 T_CURSOR 中返回结果.

Also below is a sample code that can get you started to call a stored procedure from C# to Oracle. PKG_COLLECTION.CSP_COLLECTION_HDR_SELECT is the stored procedure built on Oracle accepting parameters PUNIT, POFFICE, PRECEIPT_NBR and returning the result in T_CURSOR.

using Oracle.DataAccess;
using Oracle.DataAccess.Client;

public DataTable GetHeader_BySproc(string unit, string office, string receiptno)
{
    using (OracleConnection cn = new OracleConnection(DatabaseHelper.GetConnectionString()))
    {
        OracleDataAdapter da = new OracleDataAdapter();
        OracleCommand cmd = new OracleCommand();
        cmd.Connection = cn;
        cmd.InitialLONGFetchSize = 1000;
        cmd.CommandText = DatabaseHelper.GetDBOwner() + "PKG_COLLECTION.CSP_COLLECTION_HDR_SELECT";
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.Add("PUNIT", OracleDbType.Char).Value = unit;
        cmd.Parameters.Add("POFFICE", OracleDbType.Char).Value = office;
        cmd.Parameters.Add("PRECEIPT_NBR", OracleDbType.Int32).Value = receiptno;
        cmd.Parameters.Add("T_CURSOR", OracleDbType.RefCursor).Direction = ParameterDirection.Output;

        da.SelectCommand = cmd;
        DataTable dt = new DataTable();
        da.Fill(dt);
        return dt;
    }
}
