c# - 数组不支持类型 System.String

Question

我一直在阅读有关反序列化 json 的线程，并尝试了多种方法来实现它，但似乎无法实现。 这是我到目前为止所做的:

类

public class oVesselMovement : oVMLocation, IWPConditions, IVessel, IStatus      
{
     public int wpID { get; set; }
     public string charts { get; set; }
     public string latNS { get; set; }
     public string longEW { get; set; }
     public string course { get; set; }
     public double toNextWPNM { get; set; }
     public double toGoNM { get; set; }
     public string eda { get; set; }
     public string eta { get; set; }
}

根类

public class RootVM
{
    public List<oVesselMovement> jsnObj { get; set; }
}

JSON

{"jsnObj":[{"vmID":"1","charts":"2111","latNS":"10°29.10 N","longEW":"123°25.83 E","course":"420°","toNextWPNM":0,"toGoNM":"27","eda":"12-15-2016","eta":"11:01"},{"vmID":"2","charts":"2211","latNS":"11°29.10 N","longEW":"124°25.83 E","course":"420°","toNextWPNM":0,"toGoNM":"27","eda":"12-15-2016","eta":"11:01"}]}

反序列化

[WebMethod]
public void saveVMDT(string jsnObj)
{
    RootVM rootObj = new JavaScriptSerializer().Deserialize<RootVM>(jsnObj);
    foreach (var obj in rootObj.jsnObj)
    {
        try
        {
            ...
    }

我也试过转换 List<oVesselMovement> jsnObj { get; set; }到 oVesselMovement[] jsnObj但无济于事。

我一直收到这个错误:

"{"Message":"Type \u0027System.String\u0027 is not supported for deserialization of an array."....

如有任何帮助，我们将不胜感激。

toGoNM 是字符串，不是数字。您需要使用正确的类型，在 C# 端或 JSON 端修复它。您在 C# 类中有 wpID，但在 JSON 中有 vmID；又一次，错误的类型。
