1. SqlServer 数据类型对应.Net 的 SqlDbType数据类型

public string DBTypeToDotNetDBType(string DBType)
   {
    switch (DBType)
    {
     case "bigint": return "System.Data.SqlDbType.BigInt";
     case "binary": return "System.Data.SqlDbType.Binary";
     case "bit": return "System.Data.SqlDbType.Bit";
     case "char": return "System.Data.SqlDbType.Char";
     case "datetime": return "System.Data.SqlDbType.DateTime";
     case "decimal": return "System.Data.SqlDbType.Decimal";
     case "float": return "System.Data.SqlDbType.Float";
     case "image": return "System.Data.SqlDbType.Image";
     case "int": return "System.Data.SqlDbType.Int";
     case "money": return "System.Data.SqlDbType.Money";
     case "nchar": return "System.Data.SqlDbType.NChar";
     case "ntext": return "System.Data.SqlDbType.NText";
     case "numeric": return "System.Data.SqlDbType.Decimal";
     case "nvarchar": return "System.Data.SqlDbType.NVarChar";
     case "real": return "System.Data.SqlDbType.Real";
     case "uniqueidentifier": return "System.Data.SqlDbType.UniqueIdentifier";
     case "smalldatetime": return "System.Data.SqlDbType.SmallDateTime";
     case "smallint": return "System.Data.SqlDbType.SmallInt";
     case "smallmoney": return "System.Data.SqlDbType.SmallMoney";
     case "text": return "System.Data.SqlDbType.Text";
     case "timestamp": return "System.Data.SqlDbType.Timestamp";
     case "tinyint": return "System.Data.SqlDbType.TinyInt";
     case "varbinary": return "System.Data.SqlDbType.VarBinary";
     case "varchar": return "System.Data.SqlDbType.VarChar";
     case "variant": return "System.Data.SqlDbType.Variant";
     case "udt": return "System.Data.SqlDbType.Udt";
     default:
      return "";
    }
   }
