如何将小数属性发布到Web API 2? [英] How to post a decimal property to Web API 2?

问题描述

我将JSON对象发布到Web api 2(使用Angular)，如下所示:

I am posting a JSON object to web api 2 (using Angular) as follows:

var request = $http({
    method: "POST",
    url: "http://localhost:52389/odata/Venues",
    data: {Address: "my address", Latitude: 72.17}
});

此消息已发布到Web api操作:

This is being posted to the web api action:

public IHttpActionResult Post(Venue venue)

地点具有以下属性:

 public class Venue
    {
        [Key]
        public int VenueId { get; set; }

        [DataMember]        
        public string Address { get; set; }

        [DataMember]
        public decimal? Latitude { get; set; }
    }

如果我从发布的JSON对象中删除了谷歌纵横，则可以正常运行，但是对于谷歌纵横对象，api操作中的会场参数将变为 null .如何最好地处理这种十进制?类型?

If I remove Latitude from the JSON object being posted, then this works, but with the Latitude object, the venue parameter in the api action becomes null. How do I best handle this decimal? type?

推荐答案

设法通过在小数点后加上引号来使它起作用:

Managed to get this working by putting the decimal in quotes:

var request = $http({
    method: "POST",
    url: "http://localhost:52389/odata/Venues",
    data: {Address: "my address", Latitude: "72.17"}
});

或者如果您有一个角度数字 latNum ，那么 latNum.toString()将起作用

Or if you have an angular number, latNum, then latNum.toString() will work
