使用反射机制将一个类实例的值赋给DataTable某一行

类中的字段类型和数据库(datatable)中的字段类型需要一直,大小写无关. 类中的可以有datatable没有的属性

源代码如下：

  /**//// <SUMMARY>
        /// 依据反射机制从bean中取值赋给datatable的某行
        /// </SUMMARY>   
        /// <PARAM name="obj" />要实例的对象   
        /// <PARAM name="dataTable" />DataTable
        /// <PARAM name="row" />要读取DataTable行的序号   
        public static void InstanBeanFromDataTable(Object obj, DataTable dataTable, int row)
        {
            //指定行不存在   
            if (dataTable.Rows.Count < (row + 1))
            {
                throw new Exception("指定行不存在!");
            }

            //DataTable列为空!
            if (dataTable.Columns.Count < 1)
            {
                throw new Exception("DataTable列为空!");
            }


            Type type = obj.GetType();                                  //获取对象类型
            PropertyInfo[] pInfos = type.GetProperties();
            try
            {
                for (int i = 0; i < dataTable.Columns.Count; i++)                         //循环所有列
                {
                    for (int j = 0; j < pInfos.Length; j++)                               //循环所有属性
                    {
                        //比较的作用是防止数据库列名的大小写和属性的大小写不一致
                        if (dataTable.Columns[i].ColumnName.ToLower() == pInfos[j].Name.ToLower())
                        {
                            PropertyInfo pInfo = type.GetProperty(pInfos[j].Name);     //反射机制,动态检索类属性

                            object beanValue = pInfo.GetValue(obj, null);
                            //不同的基本数据类型,比如用Convert方法转换成对应类型的值 
                            if (!Convert.IsDBNull(beanValue) && beanValue.ToString() != null)    //如果数据集中此列有值   
                            {
                                dataTable.Rows[row][i] = beanValue;
                            }
                            else
                            {
                                dataTable.Rows[row][i] = DBNull.Value;     
                            }

                            break;
                        }
                    }
                }
            }
            catch (Exception ex)
            {                                                    //不捕获异常,异常抛出由开发人员处理   
                throw ex;
            }
        }
