Question

RenderTemplate方法

public static string RenderTemplate(string json, string template)
{
    try
    {
        dynamic obj = JsonConvert.DeserializeObject(json);
        return Render.StringToString(template,obj);
    }
    catch (Exception e)
    {
        throw e;
    }
}

Json

[  
    {  
       "Item":"Some Item",
       "Unit":"10x10",
       "Quantity":3.0,
       "Amount":0.0,
       "ExpiryDate":"2018-09-07T00:00:00",
       "NumberOfDaysToExpiry":79,
       "lessThan14":false
   }
]

案例1 与模板

{{#.}}
    {{Item}}
{{/.}}

工作正常

案例2 与模板

{{#.}}
    {{#lessThan14}} {{Unit}}, {{Quantity}}, {{Amount}}, {{ExpiryDate}}, {{NumberOfDaysToExpiry}} {{/lessThan14}}
{{/.}}

工作正常

案例3 与模板

{{#.}}
    {{lessThan14}}
{{/.}}

打印出 False ，这是错误的，因为胡须布尔不评估任何字母是否为大写字母，仍然可以解决逻辑错误

案例4 与模板

{{#.}}
    {{#lessThan14}} {{Item}} {{/lessThan14}}
{{/.}}

在这种情况下，程序无法引发异常

我想念什么？因为这在 .net 的 nustache 中起作用，但是对于 .net core

的失败

nustache.core未评估布尔值
