C#后端之CodeDom在内存中创建对象最简明的讲解（中）最后附源码

核心源码再下里，这一篇只有各个实体和反射扩展方法

中篇就干点正事儿吧。

先把几个实体类放上来拿去用。

字段是这里

using System;
using System.CodeDom;

namespace CodeMacker
{
    public class FieldEntity
    {
        public FieldEntity(string fieldName,Type fieldType)
        {
            this.Name = fieldName;
            this.Type = fieldType;
        }
        /// <summary>
        /// 字段名称
        /// </summary>
        public string Name { get; private set; }
        /// <summary>
        /// 字段类型
        /// </summary>
        public Type Type { get; private set; }
        /// <summary>
        /// 默认初始参数
        /// </summary>
        public object DefaultValue { get; set; } = default;
        /// <summary>
        /// 字段注释
        /// </summary>
        public string Comment { get; set; } = null;
        /// <summary>
        /// 字段类型，默认公开
        /// </summary>
        public MemberAttributes Attr { get; set; } = MemberAttributes.Public | MemberAttributes.Final;

    }
}

属性是这里

using System;
using System.CodeDom;

namespace CodeMacker
{
    public class PropertyEntity 
    {
        public PropertyEntity(string propertyName, Type propertyType)
        {
            this.Name = propertyName;
            this.Type = propertyType;
        }
        /// <summary>
        /// 属性名称
        /// </summary>
        public string Name { get; private set; }
        /// <summary>
        /// 属性类型
        /// </summary>
        public Type Type { get; private set; }
        /// <summary>
        /// 注释
        /// </summary>
        public virtual string Comment { get; set; } = null;
        /// <summary>
        /// 包含Set
        /// </summary>
        public bool HasSet { get; set; } = true;
        /// <summary>
        /// 包含Get
        /// </summary>
        public bool HasGet { get; set; } = true;
        /// <summary>
        /// 属性类型，默认公开
        /// </summary>
        public MemberAttributes Attr { get; set; } = MemberAttributes.Public | MemberAttributes.Final;
    }
}

方法是这里

namespace CodeMacker
{
    public class MethodEntity
    {
        /// <summary>
        /// 方法体
        /// </summary>
        public string Method { get; set; }
        /// <summary>
        /// 方法注释
        /// </summary>
        public string Comment { get; set; }
    }
}

构造函数是这里

using System;
using System.CodeDom;
using System.Collections.Generic;

namespace CodeMacker
{
    public class ConstructorEntity
    {
        /// <summary>
        /// 参数级
        /// </summary>
        public List<ParamInfo> Params { get; set; }

        /// <summary>
        /// 构造函数类型
        /// </summary>
        public MemberAttributes Attr { get; set; } = MemberAttributes.Public | MemberAttributes.Final;
    }

    public class ParamInfo
    {
        public ParamInfo(Type paramType, string name)
        {
            ParamType = paramType;
            Name = name;
        }
        /// <summary>
        /// 类型
        /// </summary>
        public Type ParamType { get; private set; }
        /// <summary>
        /// 名称
        /// </summary>
        public string Name { get; private set; }
        /// <summary>
        /// 赋值名称
        /// </summary>
        public string ReferenceName { get; private set; }
    }
}

反射是这里

using System.Reflection;

namespace CodeMacker
{
    public static class CodeMackerReflection
    {
        public static FieldInfo GetField(this object obj, string fieldName, BindingFlags bindingAttr = BindingFlags.Public | BindingFlags.Instance | BindingFlags.NonPublic)
            => obj.GetType().GetField(fieldName, bindingAttr);

        public static FieldInfo[] GetFields(this object obj, BindingFlags bindingAttr = BindingFlags.Public | BindingFlags.Instance | BindingFlags.NonPublic)
            => obj.GetType().GetFields(bindingAttr);



        public static PropertyInfo GetPropertyInfo(this object obj, string propertyName, BindingFlags bindingAttr = BindingFlags.Public | BindingFlags.Instance | BindingFlags.NonPublic)
            => obj.GetType().GetProperty(propertyName, bindingAttr);

        public static PropertyInfo[] GetPropertysInfo(this object obj, BindingFlags bindingAttr = BindingFlags.Public | BindingFlags.Instance | BindingFlags.NonPublic)
            => obj.GetType().GetProperties(bindingAttr);



        public static MethodInfo GetMethod(this object obj, string methodName, BindingFlags bindingAttr = BindingFlags.Public | BindingFlags.Instance | BindingFlags.NonPublic)
            => obj.GetType().GetMethod(methodName, bindingAttr);


        public static MethodInfo[] GetMethods(this object obj, BindingFlags bindingAttr = BindingFlags.Public | BindingFlags.Instance | BindingFlags.NonPublic)
            => obj.GetType().GetMethods(bindingAttr);

    }
}

附一张项目截图

 可以看出除了第一个Macker其他都放上来了。

好像也写了不少，啊哈哈哈哈哈。自己骗自己。

重头戏就放到（下）吧

下一定是特别长的一章，嗯，一定是。

顺路再给自己创造个流量，虽然也不知道能干吗

using System;
using System.CodeDom;

namespace CodeMacker
{
    public class FieldEntity
    {
        public FieldEntity(string fieldName,Type fieldType)
        {
            this.Name = fieldName;
            this.Type = fieldType;
        }
        /// <summary>
        /// 字段名称

        public string Comment { get; set; } = null;
        /// <summary>
        /// 字段类型，默认公开
        /// </summary>
        public MemberAttributes Attr { get; set; } = MemberAttributes.Public | MemberAttributes.Final;
