Getting Array inside of an Array from json ConfigFile using Configuration Builder in C#-CodePudding

I am unable to access the "Units" Array in the json file. I have tried pulling the Json in different ways but it does not come in. I if I myConfig.GetSection("CatalogData:Recipeints") or do a myConfig.GetSection("CatalogData:Recipeints").GetChildren() I get no values, or keys. I figure it is because I am new to this. I can get the Recipeints Array just fine. But the Units is what comes up blank.

appSetting.json

    "Recipeints": [
      {
        "MemberNo": "xxxx",
        "Data": {
          "ShortName": "ACompany",
          "StoredProc": "unknown",
          "FileName": "unknown",
          "Deliminator": "~",
          "EmailFile": 0,
          "EmailAddress": "[email protected]",
          "FTPFile": 1,
          "FTPInfo": {
            "FTPName": "ftp.something.com",
            "User": "user",
            "Password": "password"
          },
          "FileDrop": 1,
          "FileDropLocation": "\\\\FTPServer\\data\\ACompany\\outbound\\",
          "FileOrder": "MemberNo,VendorItem,Price,Description",
          "Units": [
            {
              "UnitName": "EndCust",
              "CustNos": [ "c123","c234","c345","c111" ]
            }
          ]
        }
      }
    ]
  }

CodePudding user response：

In case of console application you need to do it manually for every recipient and assign to your data object:

  Recipients = config.GetSection("Recipeints").Get<List<Recipient>>();
  for (var index = 0; index < Recipients.Count;   index)
  {
      ApiSettings[index].aboba = config.GetSection($"Recipeints:{index}:Units").Get<Unit>();
  }

BUT, as for me that`s not appsettings, that must be json file with data, which you can serialize/deserialize in easy way and what will have more sense

Try the following

{
  "Recipients": [
    {
      "MemberNo": "xxxx",
      "Data": {
        "ShortName": "ACompany",
        "StoredProc": "unknown",
        "FileName": "unknown",
        "Deliminator": "~",
        "EmailFile": 0,
        "EmailAddress": "[email protected]",
        "FTPFile": 1,
        "FTPInfo": {
          "FTPName": "ftp.something.com",
          "User": "user",
          "Password": "password"
        },
        "FileDrop": 1,
        "FileDropLocation": "\\\\FTPServer\\data\\ACompany\\outbound\\",
        "FileOrder": "MemberNo,VendorItem,Price,Description",
        "Units": [
          {
            "UnitName": "EndCust",
            "CustNos": [ "c123", "c234", "c345", "c111" ]
          }
        ]
      }
    },
    {
      "MemberNo": "xxxx",
      "Data": {
        "ShortName": "BCompany",
        "StoredProc": "unknown",
        "FileName": "unknown",
        "Deliminator": "~",
        "EmailFile": 0,
        "EmailAddress": "[email protected]",
        "FTPFile": 1,
        "FTPInfo": {
          "FTPName": "ftp.something.com",
          "User": "user",
          "Password": "password"
        },
        "FileDrop": 1,
