1、最简单的方式，反射+泛型

优点：字段修改时，无需更改代码，只需要更新实体即可

缺点：因为用到反射，可能效率会稍微弱那么一点点，没有实际用太多字段测试

public static cClass ParentCopyToChild<pClass,cClass>(pClass parent) where cClass: class,pClass,new()
{
//ChildClass child = new ChildClass();
cClass child = new cClass(); var ParentType = typeof(pClass); var Properties = ParentType.GetProperties(); foreach (var Propertie in Properties)
{
if (Propertie.CanRead && Propertie.CanWrite)
{
Propertie.SetValue(child, Propertie.GetValue(parent, null), null);
}
} return child;
}

2、子类中加入赋值操作

public class TreeViewOrgEx:TreeViewOrg
{
public long ParentCode = 0;
public string TypeName = string.Empty; //树开启多选框时，此属性决定是否默认选中
public bool isChecked;
//树开启多选框时，此属性决定多选框是否禁用
public bool chkDisabled;
//树是否默认展开
public bool open = true; public int ISRole = 0; //需要一个默认构造函数
public TreeViewOrgEx()
{ } public TreeViewOrgEx(TreeViewOrg orgBase)
{
this.ID = orgBase.ID;
this.OrgCode = orgBase.OrgCode;
this.OrgName = orgBase.OrgName;
this.OrgLevel = orgBase.OrgLevel;
this.OrgType = orgBase.OrgType;
this.SourceCode = orgBase.SourceCode;
this.UpdateTime = orgBase.UpdateTime;
}
}

赋值

TreeViewOrg tempOrg = new TreeViewOrg();tempOrg.OrgCode = 10000000000;TreeViewOrgEx orgEx = new TreeViewOrgEx(tempOrg);orgEx.ParentCode = 20000000000;

3、写方法操作

public void TreeViewOrgToTreeViewOrgEx(TreeViewOrg org, TreeViewOrgEx orgEx)
{
orgEx.ID = org.ID;
orgEx.OrgCode = org.OrgCode;
orgEx.OrgName = org.OrgName;
orgEx.OrgLevel = org.OrgLevel;
orgEx.OrgType = org.OrgType;
orgEx.SourceCode = org.SourceCode;
orgEx.UpdateTime = org.UpdateTime;
}
