将数据显示到调试控制台 [英] Display data to Debug Console

问题描述

我正在为UWP编写应用程序

I writing app for UWP

我有这个代码

var p = await wc.GetProducts(new Dictionary<string, string>() {
            { "orderby", "id" }, { "filter[search]", "1884" }
             });

我试图像这样显示字典中的数据.

I try to display data from dictionary like this.

Debug.WriteLine("There");

        Debug.WriteLine(p.products);

但这不起作用.

如何显示字典数据?

推荐答案

使用以下扩展类(需要Newtonsoft JSON库)，您可以获取具有或不具有可读格式的任何对象的JSON字符串.

Using the below extension class (Requires Newtonsoft JSON library) you can get a JSON string of any object either with or without readable formatting.

使用该类获取可读的JSON字符串；

Using the class to get a readable JSON string;

var p = await wc.GetProducts(new Dictionary<string, string>() {
    { "orderby", "id" }, { "filter[search]", "1884" }
    });

var jsonString = p.ToFormattedJsonString();

Debug.WriteLine(jsonString);

使用该类获取不带格式的纯JSON字符串；

Using the class to get a plain JSON string without format;

var p = await wc.GetProducts(new Dictionary<string, string>() {
    { "orderby", "id" }, { "filter[search]", "1884" }
    });

var jsonString = p.ToJsonString();

Debug.WriteLine(jsonString);

您也可以通过添加自己的扩展方法(例如下面的内容)简化上面的内容；

You can also simplfy the above by adding your own extension method such as the below;

public static void ToDebug(this object data)
{
    Debug.WriteLine(data.ToFormattedJsonString());
}

扩展类；

using System.Text;
using Newtonsoft.Json;

namespace System
{
    public static class JsonExtensions
    {
        public static string ToFormattedJsonString(this object obj, bool indentWithTab)
        {
            return indentWithTab
                ? ToFormattedJsonString(obj, "\t")
                : ToFormattedJsonString(obj);
        }

        public static string ToFormattedJsonString(this object obj, string indentString = "  ")
        {
            return FormatJson(obj.ToJsonString(), indentString);
        }

        public static string ToJsonString(this object obj)
        {
            return JsonConvert.SerializeObject(obj);
        }

        public static T DeserializeJsonString<T>(this string jsonString)
        {
            return JsonConvert.DeserializeObject<T>(jsonString);
        }

        private static string FormatJson(string jsonString, string indentString)
        {
            var indent = 0;
            var quoted = false;
            var builder = new StringBuilder();
            for (var i = 0; i < jsonString.Length; i++)
            {
                var character = jsonString[i];
                switch (character)
                {
                    case '{':
                    case '[':
                        builder.Append(character);
                        if (!quoted)
                        {
                            builder.AppendLine();
                            builder.RepeatAppend(++indent, indentString);
                        }
                        break;
                    case '}':
                    case ']':
                        if (!quoted)
                        {
                            builder.AppendLine();
                            builder.RepeatAppend(--indent, indentString);
                        }
                        builder.Append(character);
                        break;
                    case '"':
                        builder.Append(character);
                        bool escaped = false;
                        var index = i;
                        while (index > 0 && jsonString[--index] == '\\')
                            escaped = !escaped;
                        if (!escaped)
                            quoted = !quoted;
                        break;
                    case ',':
                        builder.Append(character);
                        if (!quoted)
                        {
                            builder.AppendLine();
                            builder.RepeatAppend(indent, indentString);
                        }
                        break;
                    case ':':
                        builder.Append(character);
                        if (!quoted)
                            builder.Append(" ");
                        break;
                    default:
                        builder.Append(character);
                        break;
                }
            }
            return builder.ToString();
        }

        public static StringBuilder RepeatAppend(this StringBuilder builder, int count, string format,
            params object[] parameters)
        {
            if (count <= 0 || string.IsNullOrEmpty(format))
                return builder;

            for (int i = 0; i < count; i++)
            {
                builder.AppendFormat(format, parameters);
            }

            return builder;
        }
    }
}
