我正在使用Newtonsoft库(Json.Net)从文件中解析JSON对象。我在jsonlint.com验证了JSON,它是有效的。
但是当我说:
using (StreamReader sr = new StreamReader(path))
{
json = await sr.ReadToEndAsync();
}
ContactsCollection = JsonConvert.DeserializeObject<List<Contact>>(json); //error
我收到错误:
解析值后,遇到意外字符:6。路径'[0]
所以我在json = await sr.ReadToEndAsync();
放了一个断点,显示的JSON值为:
"\0{\0\"\0F\0i\0r\0s\0t\0N\0a\0m\0e\0\"\0:\0\"\0N\0i\0k\0h\0\"\0,\0\"\0L\0a\0s\0t\0N\0a\0m\0e\0\"\0:\0\"\0A\0N\0S\0\"\0,\0\"\0D\0a\0t\0e\0O\0f\0B\0i\0r\0t\0h\0\"\0:\0\"\01\02\0/\07\0/\01\09\08\09\0 \01\02\0:\00\00\0:\00\00\0 \0A\0M\0\"\0,\0\"\0W\0e\0i\0g\0h\0t\0\"\0:\01\06\08\0.\00\0,\0\"\0H\0e\0i\0g\0h\0t\0\"\0:\01\06\08\0.\00\0,\0\"\0P\0h\0o\0n\0e\0\"\0:\0\"\0(\08\00\05\0)\0 \02\05\01\0-\01\00\01\05\0\"\0}\0]\0"
这是我的实际JSON:
[{
"FirstName":"Nikh",
"LastName":"ANS",
"DateOfBirth":"12/7/1989 12:00:00 AM",
"Weight":168.0,
"Height":168.0,
"Phone":"(805) 251-1015"
}]
这是我的联系人课程:
public class Contact : INotifyPropertyChanged
{
private string _firstName;
public string FirstName
{
get { return _firstName; }
set
{
_firstName = value;
NotifyPropertyChanged("FirstName");
}
}
private string _lastName;
public string LastName
{
get { return _lastName; }
set
{
_lastName = value;
NotifyPropertyChanged("LastName");
}
}
private string _dateOfBirth;
public string DateOfBirth
{
get { return _dateOfBirth; }
set
{
_dateOfBirth = value;
NotifyPropertyChanged("DateOfBirth");
}
}
private double _weight;
public double Weight
{
get { return _weight; }
set
{
_weight = value;
NotifyPropertyChanged("Weight");
}
}
private double _height;
public double Height
{
get { return _height; }
set
{
_height = value;
NotifyPropertyChanged("Height");
}
}
private string _phone;
public string Phone
{
get { return _phone; }
set
{
_phone = value;
NotifyPropertyChanged("Phone");
}
}
public event PropertyChangedEventHandler PropertyChanged;
private void NotifyPropertyChanged(String info)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(info));
}
}
}
有谁知道可能出现的问题?

这看起来像编码问题。我打赌您的文件以UTF-16编码保存,但您正在将其读作UTF-8。 (UTF-8是StreamReader
的默认编码。)这可以解释为什么在读取JSON值的中间有各种\0
个字符,以及为什么Json.Net在解析它时遇到问题。初始化StreamReader
时尝试指定编码:
using (StreamReader sr = new StreamReader(path, Encoding.Unicode, true))
{
...
}
或者,确保使用UTF-8编码保存您的JSON文件。

检查流路径是否正确设置了其位置。也许在调用path.Position = 0;
sr.ReadToEndAsync();
