我需要帮助在mvc应用程序的剃刀视图中将可以为空的十进制字段格式化为货币(带有美元符号和逗号).下面是我的模态和视图代码.

型号:

[Display(Name = "Eligible Amount")]
[RequiredIfProjectEngineerSelected("ProjectEngineerId", "", ErrorMessage = "Eligible Amount field is Required")]        
[DisplayFormat(DataFormatString = "{0:c}")]        
public decimal? EligibleAmount { get; set; }

查看:

@{var formated = String.Format("{0:c}",  decimal)decimal.Parse(@Model.project.ProjectTotalCost.HasValue ? @Model.project.ProjectTotalCost.Value.ToString() : ""));}
@Html.TextBoxFor(model => model.project.ProjectTotalCost, new { @Value = formatted})

它在TextBoxFor控件中显示格式化的货币值.但是我在这里遇到的问题是,当我尝试更新值时,得到验证错误,说"值不匹配格式".
