C#.NET数据类型(Type)与DbType的对应关系

C# Code:

/// <summary>
/// .NET数据类型与DbType对应关系
/// </summary>
public static IDictionary<Type, DbType> NetType2DbTypeMapping
{
get
{
IDictionary<Type, DbType> map = new Dictionary<Type, DbType>();

map[typeof(object)] = DbType.Object;
map[typeof(byte)] = DbType.Byte;
map[typeof(sbyte)] = DbType.SByte;
map[typeof(short)] = DbType.Int16;
map[typeof(ushort)] = DbType.UInt16;
map[typeof(int)] = DbType.Int32;
map[typeof(uint)] = DbType.UInt32;
map[typeof(long)] = DbType.Int64;
map[typeof(ulong)] = DbType.UInt64;
map[typeof(float)] = DbType.Single;
map[typeof(double)] = DbType.Double;
map[typeof(decimal)] = DbType.Decimal;
map[typeof(bool)] = DbType.Boolean;
map[typeof(string)] = DbType.String;
map[typeof(char)] = DbType.StringFixedLength;
map[typeof(Guid)] = DbType.Guid;
map[typeof(DateTime)] = DbType.DateTime;
map[typeof(DateTimeOffset)] = DbType.DateTimeOffset;
map[typeof(byte[])] = DbType.Binary;
map[typeof(byte?)] = DbType.Byte;
map[typeof(sbyte?)] = DbType.SByte;
map[typeof(short?)] = DbType.Int16;
map[typeof(ushort?)] = DbType.UInt16;
map[typeof(int?)] = DbType.Int32;
map[typeof(uint?)] = DbType.UInt32;
map[typeof(long?)] = DbType.Int64;
map[typeof(ulong?)] = DbType.UInt64;
