使用.Net Core 3.0 Blazor应用程序反序列化json时，我遇到了一些麻烦.

I have been facing some trouble to deserialize a json using .Net Core 3.0 Blazor app.

我正在将.Net Core 3.0 Blazor与Visual Studio Preview 2019一起使用

The Framework i am using .Net Core 3.0 Blazor with Visual Studio Preview 2019

{ "cols": [ "ID", "LastName", "Firstname", "middlename", "Suffix", "Title" ], "rows": [ [ "90", "Dada", "Mama", "", "", "" ] ] }

预期结果: 我想使用blazor将这个json动态加载为Web表单中的表格.我不介意为此使用任何UI框架，例如devexpress或telerik.

Expected result: i want to load this json dynamically as a table in the web form using blazor. I don't mind to use any UI framwork for this like devexpress or telerik.

id LastNmae名中间名后缀标题

id LastNmae Firstname middlename Suffix Title

推荐答案

在Blazor上完成的步骤:

1.-将Newtonsoft添加到您的Blazor项目中(对于Blazor客户端wasm，也可能是因为Newtonsoft是netstandard):

Steps accomplish on Blazor:

1.- Add Newtonsoft to your Blazor project (for Blazor client side wasm it is also possible because Newtonsoft is netstandard):

dotnet add package Newtonsoft.Json

2.-引用库，对反序列化的对象进行反序列化和迭代:

2.- Referencing library, deserializing and iterating over deserialized objects:

@page "/counter" @using Newtonsoft.Json <table > <tr> @foreach (var c in dyn.cols) { <td style="border: 1px solid black;">@c.Value</td> } </tr> @foreach (var r in dyn.rows) { <tr> @foreach (var d in r) { <td style="border: 1px solid black;">@d.Value</td> } </tr> } </table> @code { dynamic dyn; string json_str = @" your json "; protected override void OnInitialized() { dyn = JsonConvert.DeserializeObject(json_str); } }

结果:

示例的整个json:

@code { dynamic dyn; string json_str = @" { ""cols"": [ ""ID"", ""LastName"", ""Firstname"", ""middlename"", ""Suffix"", ""Title"" ], ""rows"": [ [ ""90"", ""Dada"", ""Mama"", """", """", """" ], [ ""91"", ""Dada1"", ""Mama1"", """", """", """" ], ] } ";
