reflection - PropertyInfo c#没有返回对象的成员

Question

我正在尝试使用 PropertyInfo 通过一个类进行交互并从中创建一个数据表。但是它不返回任何值。我有点难过；

public class thetransactions
{
    public string FirstName;
    public string Surname;
    public string PreviousOwner;
    public string NewOwner;
    public string postcode;
    public string[] FileName;
}

然后用这段代码做跑腿工作；

theTransactions[] thetransactions = new theTransactions[10];
thetransactions[0] = JsonConvert.DeserializeObject<theTransactions>(mydatastring);

PropertyInfo[] properties = thetransactions.GetType().GetElementType().GetProperties();
DataTable sampletable = new DataTable();
DataColumn dc = null;

foreach (PropertyInfo pi in properties)
{
    dc = new DataColumn();
    dc.ColumnName = pi.Name;
    dc.DataType = pi.PropertyType;
    sampletable.Columns.Add(dc);
}

Answer 1

问题是您在类中定义普通变量thetransactions而不是属性：

public class thetransactions
{
    public string FirstName{get;set;}
    public string Surname{get;set;}
    public string PreviousOwner{get;set;}
    public string NewOwner{get;set;}
    public string postcode{get;set;}
    public string[] FileName{get;set;}
}
