因为这个我的项目没有应用框架，应用了 sqlite 数据库。前面的业务可想而知会应用多少拼接 sql，这就会相当麻烦 一旦数据库扭转 就要改很多货色。
所以根底的就是封装生成 sql。须要应用反射和自定义的个性。自定义个性在于“绑定数据库列名”和“绑定业务格局”
一、业务一 — 主动生成 sql
1. 首先是实体对应的表:[个性 –》TableNameAttr]
using System;
using System.Collections.Generic;
using System.Text;
namespace PublicLibrary.attr
{
// 数据库表名
[AttributeUsage(AttributeTargets.Class, AllowMultiple = true)]
public class TableNameAttr: Attribute{
string value;
public TableNameAttr(string value)
{this.Value = value;}
public string Value {get => value; set => this.value = value;}
}}
2. 其次是实体字段对应的列名:[个性 –》TableFieldAttr]
using System;
namespace PublicLibrary.attr
{
// 查问 新增 批改的注解
[AttributeUsage(AttributeTargets.Field, AllowMultiple = true)]
public class TableFieldAttr:Attribute
{
//bool 是 boolean 的类型
// 是否存在的字段 ==> 针对查问
private bool isExist =true;
// 数据库列名
private string columName;
// 字符串类型
private string jdbcType;
// 默认值
private string value;
/* // 新增 批改 选着性操作的字段
private bool selective;*/
// 须要自定义的数据库函数
private bool definedFunc;
// 是否主键
private bool primaryKey =false;
// 函数的表达式
private string patternStr;
// 是否更新 默认为 true
private bool isUpdate =true;
public TableFieldAttr(string columName)
{this.ColumName = columName;}
// 字段数据库不存在
public TableFieldAttr(bool isExist)
{this.IsExist = false;}
// 行数据列名 默认值
public TableFieldAttr(string columName, string value)
{
this.ColumName = columName;
this.Value = value;
}
public TableFieldAttr(string columName, string value, string jdbcType,bool definedFunc, bool primaryKey, string patternStr)
{
this.ColumName = columName;
this.DefinedFunc = definedFunc;
this.JdbcType = jdbcType;
this.DefinedFunc = definedFunc;
this.PrimaryKey = primaryKey;
this.PatternStr = patternStr;
this.Value = value;
}
public TableFieldAttr(string columName, string value, string jdbcType,bool definedFunc, bool primaryKey, string patternStr,bool isUpdate)
{
this.ColumName = columName;
this.DefinedFunc = definedFunc;
this.JdbcType = jdbcType;
this.DefinedFunc = definedFunc;
this.PrimaryKey = primaryKey;
this.PatternStr = patternStr;
this.Value = value;
this.IsUpdate = isUpdate;
}
public bool IsExist {get => isExist; set => isExist = value;}
public string ColumName {get => columName; set => columName = value;}
public string JdbcType {get => jdbcType; set => jdbcType = value;}
public string Value {get => value; set => this.value = value;}
public bool DefinedFunc {get => definedFunc; set => definedFunc = value;}
public bool PrimaryKey {get => primaryKey; set => primaryKey = value;}
public string PatternStr {get => patternStr; set => patternStr = value;}
public bool IsUpdate {get => isUpdate; set => isUpdate = value;}
}}
3. 再就是创立 sql 的公共办法:

SQLiteSqlUtils.CreateInsertSql(record)
业务 2. 针对导入 excel
如法炮制 须要什么？须要列的下标 列内容非空验证 重复性验证 格局验证 长度验证
1. 自定义特效
using System;

public class ColumnInfoAttr:Attribute{
// 地位
int index = -1;
// 长度
int length = 32;
// 是否为空
bool nullable = false;
// 工夫格局
string dateFormat = "";
// 正则表单式 验证数据格式
string pattern = "";
public ColumnInfoAttr(int index, int length){
this.index = index;
this.length = length;
}
public ColumnInfoAttr(int index, int length, bool nullable)
{
this.index = index;
this.length = length;
this.nullable = nullable;
}
public ColumnInfoAttr(int index, int length, bool nullable,string dateFormat)
{
this.index = index;
this.length = length;
this.nullable = nullable;
this.dateFormat = dateFormat;
}
public ColumnInfoAttr(int index, int length, bool nullable, string dateFormat, string pattern)
{
this.index = index;
this.length = length;
this.nullable = nullable;
this.dateFormat = dateFormat;
this.Pattern = pattern;
}
public int Index {get => index; set => index = value;}
public int Length {get => length; set => length = value;}
public bool Nullable {get => nullable; set => nullable = value;}
public string DateFormat {get => dateFormat; set => dateFormat = value;}
