DbType与Type之间的转换1. DbType ==>Type:public static DbType TypeToDbType(Type t){ DbType dbt; try { dbt = (DbType)(typeof(DbType), ); } catch { dbt = ; } return dbt;}

2. Type ==> DbType:static Type ConvertType(DbType dbType){ Type toReturn = typeof(DBNull); switch (dbType) { ca 64: toReturn = typeof(UInt64); break; ca 64: toReturn = typeof(Int64); break; ca 32: toReturn = typeof(Int32); break; ca 32: toReturn = typeof(UInt32); break; ca : toReturn = typeof(float); break; ca : ca me: ca : toReturn = typeof(DateTime); break; ca : ca FixedLength: ca ring: ca ringFixedLength: toReturn = typeof(string); break; ca 16: toReturn = typeof(UInt16); break; ca 16: toReturn = typeof(Int16); break; ca : toReturn = typeof(byte); break; ca : toReturn = typeof(object); break; ca eric: ca l: toReturn = typeof(decimal); break; ca cy: toReturn = typeof(double); break; ca : toReturn = typeof(byte[]); break; ca : toReturn = typeof(Double); break; ca : toReturn = typeof(Guid); break; ca n: toReturn = typeof(bool); break; } return toReturn;}
