{
using( SqlConnection myConnection = GetSqlConnection() )
{
SqlCommand myCommand = new SqlCommand(databaseOwner + ".cs_Post_CreateUpdate", myConnection);
myCommand.CommandType = CommandType.StoredProcedure;
// Add parameters
//
myCommand.Parameters.Add("@SectionID", SqlDbType.Int).Value = picture.SectionID;
myCommand.Parameters.Add("@ParentID", SqlDbType.Int).Value = picture.ParentID;

myCommand.Parameters.Add("@IsLocked", SqlDbType.Bit).Value = picture.IsLocked;
myCommand.Parameters.Add("@PostType", SqlDbType.Int).Value = picture.PostType;
myCommand.Parameters.Add("@EmoticonID", SqlDbType.Int).Value = picture.EmoticonID;
myCommand.Parameters.Add("@PostAuthor", SqlDbType.NVarChar, 64).Value = picture.Username;

myCommand.Parameters.Add("@StickyDate", SqlDbType.DateTime).Value = picture.StickyDate;
myCommand.Parameters.Add(this.SettingsIDParameter());
SerializerData data = picture.GetSerializerData();
myCommand.Parameters.Add("@PropertyNames", SqlDbType.NText).Value = data.Keys;
myCommand.Parameters.Add("@PropertyValues", SqlDbType.NText).Value = data.Values;
myCommand.Parameters.Add("@PostID", SqlDbType.Int).Direction = ParameterDirection.Output;
myCommand.Parameters.Add("@ThreadID", SqlDbType.Int).Direction = ParameterDirection.Output;
myConnection.Open();
myCommand.ExecuteNonQuery();
// LN 5/27/04: try/catch added to get rid of exceptions
try
{
picture.PostID = (int) myCommand.Parameters["@PostID"].Value;
picture.ThreadID = (int) myCommand.Parameters["@ThreadID"].Value;
}
catch {}
if (picture.PostID == -1)
{
myConnection.Close();
throw new CSException(CSExceptionType.PostDuplicate);
}
myConnection.Close();
}
}然后再将相片文件存入DB
