我查看了堆栈溢出的档案，但无法得到我所得错误的答案。
整个错误是
Error 283 The best overloaded method match for 'System.Collections.Generic.List<ds_iDMS.Models.Person.SearchReturnListItem>.Add(ds_iDMS.Models.Person.SearchReturnListItem)' has some invalid arguments C:\Users\mgay.AUTOSQL\Source\Workspaces\ds_iDMS\webSites\ds_iDMS\Controllers\CustomerController.cs 242 25 ds_iDMS

我附上整个模型，因为我想确保尽可能多地为您提供信息。
我试图将错误行切换到
vm.Identities.AddRange(item)
无济于事我也试过
vm.Identities.AddRange[item]
也无法解决错误。以前有人有这个问题吗？我不完全确定如何解决这个问题，但如果你能指出我正确的方向，我会很感激
答案 0 :(得分：0)
item是SearchViewModel：
var item = new SearchViewModel();
vmReturn.Identities是List<ds_iDMS.Models.Person.SearchReturnListItem>：
public List<SearchReturnListItem> Identities { get; set; }
因此，您要么将错误的项目添加到列表中，要么将该项目添加到错误的列表中。
使用代码墙很难知道哪个是正确的或要修改什么来修复它。我建议将代码重构为更小的方法 - 这可以帮助您确定问题所在。
