Get actual values from .ToDictionary()

[kambalin]

Hello, thank you for lib. Trying to work with. From discussion #114 found out that I can use .ToDictionary(). It works well, but how to get values from dictionary? Value is not public property.

var xx = await RfcCtx.CallFunction("MAIN_FUNC",
               Input: f => f.SetField("IV_ID", id),
               Output: f => from stuct1 in f.Bind(x1 => x1.GetStructure("STRUCT1")
                       .MapTable("TABLE1", row => row.ToDictionary())
                   )
                            let items = f.Bind(
                               x1 => x1.GetStructure("STRUCT1")
                                   .MapTable("TABLE2", row => row.ToDictionary())
                               )
                            select new { Entries = stuct1, Items = items }
               )
               .IfLeftAsync(l => throw new Exception(l.Message));

foreach (var entry in xx.Entries)
{
               var entryId = entry.TryGetValue("ID") - ???
}

How to get value from?

Hi,
as you can see in your screenshot the type of field ID is actually a AbapStringValue. So you can cast the property to access the value:

var id = ((AbapStringValue) r["ID"]).Value;

This solution should be sufficient in almost all cases when you know the property type of the field.

Another - more generic approach is to use the FieldMapper of IRfcRuntime:

  IRfcRuntime rfcRuntime;  // get this from dependency injection
  rfcRuntime.FieldMapper.FromAbapValue<string>(dictionary["ID"]).Match(
      id =>
      {
          // do something with the value
      },
      (left) =>
      {
          // handle error
      }
  );

Access to IRfcRuntime is possible via IConnection or directly from dependency injection if used.

Thank you very much, casting works. Will try generic approach tomorrow.
