我的代码如下:
public void ReadListItem()
{
List<uint> lst = new List<uint>() { 1, 2, 3, 4, 5 };
string str = string.Empty;
foreach (var item in lst)
str = str + item + ",";
str = str.Remove(str.Length - 1);
Console.WriteLine(str);
}
输出:1、2、3、4、5所示
将List<uint>转换为逗号分隔的字符串的最简单方法是什么?

你可以像这样用逗号分隔列表实体:
//phones is a list of PhoneModel
var phoneNumbers = phones.Select(m => m.PhoneNumber)
.Aggregate(new StringBuilder(),
(current, next) => current.Append(next).Append(" , ")).ToString();
// Remove the trailing comma and space
if (phoneNumbers.Length > 1)
phoneNumbers = phoneNumbers.Remove(phoneNumbers.Length - 2, 2);

phoneNumbers = phoneNumbers.Remove(phoneNumbers.Length - 2, 2);
使用字符串。加入:
string.Join<string>(",", lst);
使用LINQ聚合:
lst .Aggregate((a, x) => a + "," + x);
遵循这个:
List<string> name = new List<string>();
name.Add("Latif");
name.Add("Ram");
name.Add("Adam");
string nameOfString = (string.Join(",", name.Select(x => x.ToString()).ToArray()));
Try
Console.WriteLine((string.Join(",", lst.Select(x=>x.ToString()).ToArray())));

我们可以像这样用逗号分隔列表项:
string stations =
haul.Routes != null && haul.Routes.Count > 0 ?String.Join(",",haul.Routes.Select(y =>
y.RouteCode).ToList()) : string.Empty;
