两个结果集数据格式相同,数据结构不同

1. 类定义

public class TestClassA
{
    public string Code { get; set; }
public string Name { get; set; }
}
public class TestClassB

{

public string UserCode { get; set; }
public string UserName { get; set; }
}

2.填充数据

var testClassAList = new List
{
    new TestClassA { Name="小王",Code = "001"},new TestClassA { Name="小王",Code = "002"},new TestClassA { Name="老王",Code = "003"},new TestClassA { Name="小张",Code = "001"}
};
var testClassBList = new List

{

new TestClassB { UserName="小王",UserCode = "001"},new TestClassB { UserName="小张",UserCode = "002"}

};

3.具体实现

var differentList = classAList.Where(l => !classBList.Any(t => t.UserName == l.Name && t.UserCode == l.Code));
foreach (var item in differentList)

{

Console.WriteLine($"Name: {item.Name} | Code: {item.Code}");

}
