由 烂漫一生 提交于 2021-01-27 04:47:34
问题 Does anyone know what is the DbType equivalent to SqlDbType.Bit? I am trying to convert param[0] = new SqlParameter("@Status", SqlDbType.Bit); param[0].Value = Status; to db.AddInParameter(dbCommand, "@Status", <DbType dbType>, Status); but I don't know which DbType to use to represent a single Bit.
