检查列表中的值并将其分配给C#asp.net中的字符串

您可以使用LINQ FirstOrDefault()

var location = UMSLocationDetails.FirstOrDefault(x => x.LocationName == "Rajashtan");
if (location != null)
{
    // do something with location / location.LocationName
}

var locationExists = UMSLocationDetails.Any(x => x.LocationName.ToLowerInvariant() == "rajashtan");

有了新的C#和它的空合并,参考现有的答案,生活变得更加轻松:

var locationName = UMSLocationDetails.FirstOrDefault(x => x.LocationName?.ToLowerInvariant().Trim() == "rajashtan")?.LocationName;

你可以试试这个。

string locationName = UMSLocationDetails.FirstOrDefault(l => l.LocationName == "Rajashtan")?.LocationName;

FindIndex

    string state = "Rajashtan";
    int index = UMSLocationDetails.FindIndex(c => c.LocationName == state);
    if (index >= 0) 
    string locationName = UMSLocationDetails[index].LocationName;

如果你想找到唯一的存在,然后做其他事情

    string state = "Rajashtan";
    bool exists = UMSLocationDetails.Any(c => c.LocationName == state);
    if (exists){}
