C# select语句中的Linq逻辑

我有以下代码：

List<String> AdminLocation= new List<String>();
AdminLocation.Add("Location1");
AdminLocation.Add("Location2");
AdminLocation.Add("Location3");

AdminLocation.Cast<string>().ToList()

ContactLocations = Locations
    .Where(l => l.Active == "Y").OrderBy(l => l.Name)
    .Select(l => new Location { DbLocation = l, IsChecked = false })
    .ToList();

public class Location    {
    public db.Location DbLocation { get; set; }
    public Boolean IsChecked { get; set; }
    public Boolean IsEnabled { get; set; }
}

---

这样做会有帮助吗？

我相信您可以使用

contains

检查现有查询中的列表

List<String> AdminLocation= new List<String>();
AdminLocation.Add("Location1");
AdminLocation.Add("Location2");
AdminLocation.Add("Location3");

AdminLocation.Cast<string>().ToList()

ContactLocations = Locations
    .Where(l => l.Active == "Y").OrderBy(l => l.Name)
    .Select(l => new Location { DbLocation = l, IsChecked = false, IsEnabled = AdminLocation.Contains(l.Name) })
    .ToList();

public class Location    {
    public db.Location DbLocation { get; set; }
    public Boolean IsChecked { get; set; }
    public Boolean IsEnabled { get; set; }
}

List AdminLocation=new List（）；
AdminLocation.Add（“Location1”）；
AdminLocation.Add（“Location2”）；
AdminLocation.Add（“Location3”）；
AdminLocation.Cast（）.ToList（）
联系人位置=位置
.Where（l=>l.Active==“Y”）.OrderBy（l=>l.Name）
.Select（l=>newlocation{DbLocation=l，IsChecked=false，IsEnabled=AdminLocation.Contains（l.Name）}）
.ToList（）；
公共类位置{
public db.Location DbLocation{get；set；}
公共布尔值已检查{get；set；}
公共布尔IsEnabled{get；set；}
}

ContactLocations = Locations
.Where(l => l.Active == "Y").OrderBy(l => l.Name)
.Select(l => new Location { DbLocation = l, 
                            IsChecked = false, 
                            IsEnabled = AdminLocation.Contains(l.Name) })
.ToList();

List<String> AdminLocation= new List<String>();
AdminLocation.Add("Location1");
AdminLocation.Add("Location2");
AdminLocation.Add("Location3");

AdminLocation.Cast<string>().ToList()

ContactLocations = Locations
    .Where(l => l.Active == "Y").OrderBy(l => l.Name)
    .Select(l => new Location { DbLocation = l, IsChecked = false, IsEnabled = AdminLocation.Contains(l.Name) })
    .ToList();

public class Location    {
    public db.Location DbLocation { get; set; }
    public Boolean IsChecked { get; set; }
    public Boolean IsEnabled { get; set; }
}
