I try to use Xamarin Forms (with PCL project). My scope is to make an app to consume public service (exposed via web services). I try to use TODOASMX Example of Xamarin website. The problem is the code:
static TodoItem FromASMXServiceTodoItem (ASMXService.TodoItem item)
{
return new TodoItem {
ID = item.ID,
Name = item.Name,
Notes = item.Notes,
Done = item.Done
};
}
scope of this code is to copy data from ASMX web Service (ASMXService.TodoItem ) to private domanin (TodoItem). The types are identical, but on namespace different and than the type are different.
In my case the type TodoItem is more, more , more complicated and I need to use a deep copy. Now I try to use this code for deep copy:
public static object CloneObject(object objSource)
{
//step : 1 Get the type of source object and create a new instance of that type
Type typeSource = objSource.GetType();
object objTarget = Activator.CreateInstance(typeSource);
//Step2 : Get all the properties of source object type
PropertyInfo[] propertyInfo = typeSource.GetProperties(BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance);
//Step : 3 Assign all source property to taget object 's properties
foreach (PropertyInfo property in propertyInfo)
{
//Check whether property can be written to
if (property.CanWrite)
{
//Step : 4 check whether property type is value type, enum or string type
if (property.PropertyType.IsValueType || property.PropertyType.IsEnum || property.PropertyType.Equals(typeof(System.String)))
{
property.SetValue(objTarget, property.GetValue(objSource, null), null);
}
//else property type is object/complex types, so need to recursively call this method until the end of the tree is reached
else
{
object objPropertyValue = property.GetValue(objSource, null);
if (objPropertyValue == null)
{
property.SetValue(objTarget, null, null);
}
else
{
property.SetValue(objTarget, CloneObject(objPropertyValue), null);
}
}
}
}
return objTarget;
}
but when run the code the error is:
System.MissingMethodException: Default constructor not found for type TodoASMX.Droid.MeginetOTA.excInfoByLang[]
Now the type TodoASMX.Droid.MeginetOTA.excInfoByLang[] is not modificable for me and I cannot add default constructor to this type. This type is returned by import of public WebService.
Any workaround (or solution) is appreciated.
Very thanks in advance.
