小编use*_*814的帖子

我在Visual Studio 2013中打开的每个项目现在都突然给我以下错误:

EverySingleProject.csproj:错误:项目的默认XML名称空间必须是MSBuild XML名称空间.如果项目是以MSBuild 2003格式创作的,请在元素中添加xmlns ="http://schemas.microsoft.com/developer/msbuild/2003".如果项目是以旧的1.0或1.2格式编写的,请将其转换为MSBuild 2003格式.C:\ Program Files(x86)\ MSBuild\12.0\bin\Microsoft.Common.CurrentVersion.targets

这是在文件中:

Project ToolsVersion ="12.0"DefaultTargets ="Build"xmlns ="http://schemas.microsoft.com/developer/msbuild/2003"

为什么这会失败？

我从web api获取同一对象的集合的集合.然后,我想将JSON反序列化为单个List

JSON如下:

{
  "Liverpool": [
    {
      "playerId": "LIV01",
      "name": "Adam Llana",
      "position": "Midfielder"
    },
    {
      "playerId": "LIV02",
      "name": "Daniel Sturridge",
      "position": "Forward"
    }
  ],
  "ManchesterUnited": [
    {
      "playerId": "MNU01",
      "name": "Daley Blind",
      "position": "Defender"
    },
    {
      "playerId": "MNU02",
      "name": "Romelu Lukaku",
      "position": "Forward"
    }
  ],
  "Arsenal": [
    {
      "playerId": "ARS01",
      "name": "Petr Cech",
      "position": "Goalkeeper"
    },
    {
      "playerId": "ARS02",
      "name": "Santi Cazorla",
      "position": "Midfielder"
    }
  ]
}

我想能够做的是以下因为我对集合名称不感兴趣:

public class Player
{
    public string playerId { get; set; } …
