如何使用 IConfiguration 從 appsetting.json 讀取值的子數組？

Question

我需要的是通過將名稱值與數據庫查詢中的值相匹配來獲取 GroupAssets SearchPath 值。 在這一點上，我只是試圖將 GroupAssets 拉入一個數組。

應用程序設置.json

"Production": {
    "PrintJobs": [
      {
        "SalesCategory": "5084",
        "JobType": 1,
        "SubJobType": 5014,
        "ShipVia": 5019,
        "CSR": 360,
        "SLAHours": 216,
        "DaysToArrive": 5,
        "Note": [ "" ],

        "GroupAssets": [
          {
            "Name": "MapImage",
            "SearchPath": "\\\\Server\\Path",
            "PrintAssetType": "Image",
            "ValidExtensions": [ "jpg" ]
          },
          {
            "Name": "PageImage",
            "SearchPath": "\\\\Server\\Path",
            "PrintAssetType": "Image",
            "ValidExtensions": [ "jpg" ],
            "CreativeCodes": [ "M1YV", "M1YW" ]
          },
          {
            "Name": "ItineraryPage",
            "SearchPath": "\\\\Server\\Path",
            "PrintAssetType": "Pdf",
            "ValidExtensions": [ "pdf" ],
            "CreativeCodes": [ "M1YV", "M1YW" ]
          }

        ],
     }
}

我的代碼：

var myArray = _config.GetSection("Production:PrintJobs").GetChildren();

public class PrintAssetDefns
{
   public string Name { get; set; }
   public string SearchPath { get; set; }
   public string PrintAssetType { get; set; }
   public string ValidExtensions { get; set; }
   public string CreativeCodes { get; set; }
}

Answer 1

嘗試這個

PrintAssetDefns[] MyArray = configuration.GetSection("Production:PrintJobs")
.GetChildren().First().GetSection("GroupAssets").Get<PrintAssetDefns[]>();

或者你可以獲得所有數據

PrintJob[] myArray = _config.GetSection("Production:PrintJobs").Get<PrintJob[]>();

類

public class PrintAssetDefns
{
    public string Name { get; set; }
    public string SearchPath { get; set; }
    public string PrintAssetType { get; set; }
    public List<string> ValidExtensions { get; set; }
    public List<string> CreativeCodes { get; set; }
}

public class PrintJob
{
    public string SalesCategory { get; set; }
    public int JobType { get; set; }
    public int SubJobType { get; set; }
    public int ShipVia { get; set; }
    public int CSR { get; set; }
    public int SLAHours { get; set; }
    public int DaysToArrive { get; set; }
    public List<string> Note { get; set; }
    public List<PrintAssetDefns> GroupAssets { get; set; }
}
