C# JsonConvert.DeserializeObject 没有正确填充对象

Question

JsonConvert.DeserializeObject<Language>(json) returns 属性为空的对象。我想填充 lang 对象，它应该有一些属性，例如名为 'IncreaseIndent' 和其他的字符串列表。

Indentor.json

{"VBA":[
  { "IncreaseIndent":["Public Sub *","Public Function *","If *then","While *","Do","Do while *","For *","With *","Select Case *","Sub *","Function *","* Type *","Private Sub *","Private Function *","* Enum *"]},
  { "DecreaseIndent":["End Sub","End Function","End if","Wend","Loop While *","Loop","Next","Next *","End With","End Select","End Type","End Enum"] },
  { "Exception":["Elseif *","Else","Case *","Case"]}
]}

C#

public static string FormatCode(string strCode)
{
    Language lang;
    using (StreamReader r = new StreamReader("A:/standardvba/Logic/Indentor.json"))
    {
        string json = r.ReadToEnd();
        lang = JsonConvert.DeserializeObject<Language>(json); //Inside lang every property is null
        return IndentCodePiece(strCode, lang);
    }
}

public class Language
{
    public string ProgrammingLanguage { get; set; }
    public List<string> IncreaseIndent { get; set; }
    public List<string> DecreaseIndent { get; set; }
    public List<string> Exception { get; set; }
}

Answer 1

您的 JSON 格式错误，IncreaseIndent、DecreaseIndent 和 Exception 应该是字符串列表：

{"VBA":[
    { "IncreaseIndent":["Public Sub *","Public Function *",...] },
    { "DecreaseIndent":["End Sub","End Function", ...] },
    { "Exception":["Elseif *","Else","Case *","Case"] }
]}

我在II、DI和Ex后面加了[，每个值后面加了]！

您可以在 https://jsonlint.com 页上验证 josn，您会发现验证将失败。如果引入修改我建议验证就OK了！
