我的内存不足。

CalendarModel类：

namespace Calendar
{
    class CalendarModel
    {
        [JsonProperty("name")]
        public string name { get; set; }

        [JsonProperty("date")]
        public string date { get; set; }

        [JsonProperty("title")]
        public string title { get; set; }

        [JsonProperty("mondayAM")]
        public string mondayAM { get; set; }

        [JsonProperty("mondayPM")]
        public string mondayPM { get; set; }

        [JsonProperty("tuesdayAM")]
        public string tuesdayAM { get; set; }

        [JsonProperty("tuesdayPM")]
        public string tuesdayPM { get; set; }

        [JsonProperty("wednesdayAM")]
        public string wednesdayAM { get; set; }

        [JsonProperty("wednesdayPM")]
        public string wednesdayPM { get; set; }

        [JsonProperty("thursdayAM")]
        public string thursdayAM { get; set; }

        [JsonProperty("thursdayPM")]
        public string thursdayPM { get; set; }

        [JsonProperty("fridayAM")]
        public string fridayAM { get; set; }

        [JsonProperty("fridayPM")]
        public string fridayPM { get; set; }

        [JsonProperty("saturdayAM")]
        public string saturdayAM { get; set; }

        [JsonProperty("saturdayPM")]
        public string saturdayPM { get; set; }
    }
}

我一直在崩溃

userSelection.Add(c.name)

Answer 1

仔细看看你在做什么

foreach (var addedUser in userSelection.ToArray())
{
    if (!addedUser.Contains(c.name))
    {
        userSelection.Add(c.name);
    }
}

您要在userSelection循环中添加 userSelection 测试在!addedUser.Contains

你甚至不应该这样做，但我认为ToArrray（）让它发生

所以你添加了Sally
然后马克
然后再次添加Mark，因为在循环中Mark！= Sally

您没有使用List<String> managerNames = new List<String>();

private void findManagerForSelectedDate(String dateSelected)
{
    dateSelected = dateTimePicker1.Value.ToShortDateString();

你传入dateSelected，然后用dateTimePicker1直接传递，然后你甚至不使用它

你们大多数代码对我来说都没什么意义
