Question

我正在尝试使用此行解析我的电子邮件模板。我正在使用razorengine

 public string Converttemplate(Guid RecordId, string str,string Redirecto)
    {          
        string str1 = string.Empty;
        if (Redirecto == "Quotation")
        {
            var quot = QuotationService.GetQuotationForDetails(RecordId);

            str1 = RazorEngine.Razor.Parse<QuotationForDetailsViewModel>(str, quot);
        }

        return str1;
    }

基本上str包含这样的东西

Dear @Model.CustomerId
Your QuotationId @Model.QuotationNo is created , 
Your Sincerely Admin

这将正确分析，因为@ Model.CustomerId和@ Model.QuotationNo都包含在 quot 模型中。

但如果我将@ Model.CustomerId替换为“模型模型中不存在的@ Model.CustomerName，那么它会给无法编译错误？< / p>

我确信这将在框架中处理!!我该如何解决这个问题？

如果你想支持'无效'属性名称/方法/事件......你需要使用dynamic并编写自己的包装器：

public class MyWrapper : DynamicObject
{
    private dynamic _inner;
    public MyWrapper(dynamic inner) {
        _inner = inner;
    }

    public override bool TryGetMember(
        GetMemberBinder binder, out object result)
    {
        try {
            // Dynamically invoke binder.Name on _inner (you can use reflection for example)
            // Another way is to use https://github.com/ekonbenefits/impromptu-interface:
            result = new Invocation(InvocationKind.Get, binder.Name).InvokeWithStoredArgs(_inner);
        } catch {
            // RazorEngine should ignore this.
            result = "";
        }
        return true;
    }
}

然后你只需要将该包装器提供给RazorEngine。您可以覆盖DynamicObject的更多方法并将其转发以支持更多方案（但您应该明白这一点）。
