以下是控制器

            }

            var suggestToUpdate = await _context.BerrySuggests.FirstOrDefaultAsync(s => s.BerrySuggestKey == id);
            if (await TryUpdateModelAsync<BerrySuggest>(
                suggestToUpdate,
                "",

但它犯了一个错误。所以我甚至不能检查它。以下是错误代码

“但它出错了。”-到底发生了什么？请具体说明，这很有帮助。已在浏览器中看到错误。将

@model PineBerry01.Models.BerrySuggest

更改为

@model PineBerry01.ViewModel.SuggestViewModel

时发生错误。请查看堆栈跟踪中的这一行，

InvalidOperationException:传递到ViewDataDictionary的模型项的类型为“PineBerry01.Models.BerrySuggest”，但是，此ViewDataDictionary实例需要类型为“PineBerry01.ViewModel.BerrySuggestViewModel”的模型项。

，错误自行解释

     public DateTime SuggestDate { get; set; }
