我无法解决问题,所有值都在对象的第一级很好地重新获得,但嵌套属性值会生成错误。我确信我需要调整getValue参数对象,但我不确定如何。我试图传递nestedpropertyInfoArray,propertyInfo或req作为参数,但仍然是相同的错误。任何提示?
UpdatePhoneReq req = new UpdatePhoneReq();
foreach (PropertyInfo propertyInfo in req.GetType().GetProperties())
{
if (propertyInfo.CanRead)
{
string attributValue = "";
string attributName = propertyInfo.Name;
Type attributType = propertyInfo.PropertyType;
if (attributType == typeof(XFkType))
{
PropertyInfo[] nestedpropertyInfoArray = propertyInfo.PropertyType.GetProperties();
attributValue += "{";
foreach (PropertyInfo subProperty in nestedpropertyInfoArray)
{
// --- > the GetValue below generates the error
System.Diagnostics.Debug.WriteLine(subProperty.Name + "=" + subProperty.GetValue(req, null).ToString());
attributValue += subProperty.Name + "=" + ",";
}
attributValue = attributValue.Substring(0, attributValue.Length - 1) + "}";
}
else
attributValue = propertyInfo.GetValue(req, null) == null ? "" : propertyInfo.GetValue(req, null).ToString();
System.Diagnostics.Debug.WriteLine("[" + propertyInfo.PropertyType + "]" + attributName + "=" + attributValue);
}
}

您正在传递父对象" req"要获取子属性的值,您需要首先找到属性的值并传递它以获取子属性的值。
var propertyInfoValue = propertyInfo.GetValue(req, null);
然后将此propertyInfoValue
用于subProperty
。
subProperty.GetValue(propertyInfoValue , null)
