一、创建Model层
using System;
namespace SCM.API.MODEL
{
public partial class USR_MSTR
{
public string USR_USER { get; set; }
public string USR_NAME { get; set; }
public string USR_GROUP { get; set; }
public string USR_DEPT { get; set; }
public string USR_PASSWORD { get; set; }
public string USR_LIB_PATH { get; set; }
public string USR_DEF_SITE { get; set; }
public Nullable<int> USR_WARNING_CIRCLE { get; set; }
public Nullable<short> USR_EMPLOYEE { get; set; }
public Nullable<short> USR_LOCK { get; set; }
public Nullable<short> USR_OUT { get; set; }
public string USR_AGENT { get; set; }
public string USR_ALLOW_IP { get; set; }
public string USR_CRT_BY { get; set; }
public Nullable USR_CRT_DATE { get; set; }
public string USR_POSITION { get; set; }
public string USR_MOBILE { get; set; }
public string USR_BQQ { get; set; }
public string USR_VIEW_SITES { get; set; }
public string USR_RMKS { get; set; }
public string USR_CHAR1 { get; set; }
public string USR_CHAR2 { get; set; }
public string USR_CHAR3 { get; set; }
public string USR_CHAR4 { get; set; }

public string USR_CHAR6 { get; set; }
public Nullable<decimal> USR_QTY1 { get; set; }
public Nullable<decimal> USR_QTY2 { get; set; }
}
}

foreach (byte b in ms.ToArray())
{

}
return ret.ToString();
}
#endregion
public static string Decrypt(string Text)
{
return Decrypt(Text, "MATICSOFT");
}
#region 解密
///

public static string Decrypt(string Text, string sKey)
{
DESCryptoServiceProvider des = new DESCryptoServiceProvider();
int Len;
Len = Text.Length / 2;
byte[] inputByteArray = new byte[Len];
int x, i;
for (x = 0; x < Len; x++)
{
i = Convert.ToInt32(Text.Substring(x * 2, 2), 16);
inputByteArray[x] = (byte)i;
}
des.Key = ASCIIEncoding.ASCII.GetBytes(System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(sKey, "md5").Substring(0, 8));

三、创建Dal数据访问层

}
public Dictionary<string, object> RunProcName(string sql, OracleParameter[] pars, Dictionary<string,object> dic)
