系统.MissingMethodException: Method not found: '字符串.get_Da
本文关键字:字符串 get Da MissingMethodException Method not found 系统 | 更新日期: 2023-09-27 18:14:31
我有以下类型:
public class TimeBand
{
public string DayName { get; set; }
public int customerId { get; set; }
}
和我正在创建一个包含TimeBands的列表:
var TimeBandList = new List<TimeBand>
{
new TimeBand()
{
DayName = DayOfWeek.Monday.ToString(),
customerId = 10
},
new TimeBand()
{
DayName = DayOfWeek.Tuesday.ToString(),
customerId = 11
}
.....
};
我正在使用以下内容将TimeBands加载到另一个List中:
var timeBandRange = new List<TimeBand>();
timeBandRange = TimeBandList.Where
(p => p.customerId == newCustomerId
&& p.DayName == date.DayOfWeek.ToString()).ToList();
这是工作良好,但在TimeBand类我决定改变类型的DayName属性为DayOfWeek从string所以代码变成这样:
public class TimeBand
{
public DayOfWeek DayName { get; set; }
public int customerId { get; set; }
}
var TimeBandList = new List<TimeBand>
{
new TimeBand()
{
DayName = DayOfWeek.Monday,
customerId = 10
},
new TimeBand()
{
DayName = DayOfWeek.Tuesday,
customerId = 11
}
.....
};
DateTime date = IndDate;
var timeBandRange = new List<TimeBand>();
timeBandRange = TimeBandList.Where
(p => p.customerId == parameter.customerId
&& p.DayName == date.DayOfWeek).ToList();
这个新代码现在在TimeBandList上失败了。其中行,并给出以下错误:MissingMethodException: Method not found: 'System. '字符串TimeBand.get_DayName()"。
知道为什么吗?
谢谢
也许你只需要重新编译?我在本地运行这段代码,它工作得很好。
class Program
{
static void Main(string[] args)
{
TimeBand.DoSomething();
}
}
public class TimeBand
{
public DayOfWeek DayName { get; set; }
public int customerId { get; set; }
public static void DoSomething()
{
var TimeBandList = new List<TimeBand>
{
new TimeBand()
{
DayName = DayOfWeek.Monday,
customerId = 10
},
new TimeBand()
{
DayName = DayOfWeek.Tuesday,
customerId = 11
}
};
DateTime date = DateTime.Now;
var timeBandRange = new List<TimeBand>();
timeBandRange = TimeBandList.Where
(p => p.customerId == 1
&& p.DayName == date.DayOfWeek).ToList();
}
}
我以前也遇到过同样的问题。我有一个SharePoint项目,它引用了一个类库。在。net 4.0及以上版本中,dll被插入到这个位置:C:'Windows'Microsoft.NET'assembly'GAC_MSIL'
。因此,如果您得到与上面相同的错误,那么您需要重新构建解决方案并再次在GAC_MSIL中部署DLL,否则它仍然会引用旧的DLL。
在我的情况下,问题是,我已经将库中的属性类型从string更改为int。在另一个项目中,属性变量赋值给动态变量在编译时它不会给出任何错误,但在运行时它会抛出这个错误。为了解决这个问题,我需要编译具有动态变量分配的项目,它没有任何变化。现在它运行良好。
