I'm trying to save two elements, a string and a list of strings to a binary file. I have the class set outside the main script:
}
the main script
}
[Serializable]
class SaveManager
{
public string Info;
public List<InfoSheetList> InfoSheetList ;
}
Then the function that calls it all
public void GetInfoSheet()
{
DatabaseManager.Instance.SQLiteInit();
string Info = PlayerPrefs.GetString ("Info");
string date = PlayerPrefs.GetString ("Date");
string Date=date.Replace("/","-");
string Name = PlayerPrefs.GetString ("Name");
string FilePath="C:/InfoSheets";
DatabaseManager.Instance.SQLiteInit();
InfoSheetList.Clear();
InfoSheetList= DatabaseManager.Instance.MakeInfoSheetList();
Debug.Log("How many in the list " + InfoSheetList.Count);
BinaryFormatter bf = new BinaryFormatter();
FileStream fs = File.Create(FilePath + "/" +Date+Name+"InfoSheet.gig");
Debug.Log (fs);
SaveManager sm= new SaveManager();
sm.Info=Info;
sm.InfoSheetList=InfoSheetList;
//PlayerPrefs.DeleteAll ();
bf.Serialize(fs, sm);
fs.Close();
Debug.Log(sm+ "Saved!");
Only I'm getting an exception-
SerializationException: Type 'InfoSheet' in Assembly 'Assembly-CSharp, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable.

What am I missing. The string is serializing, but the list is not.
Thanks in advance!
Alexander, you are right. All I had to do is to add System.Serializable to the Infosheet Class. After I did that it worked! Thanks!

Not able to replace entire observable collection. As it throws exception.
How do I replace entire observable collection item? The suggested answers from other threads didn't work. Tried the following. Any suggestion would help on this.
Xaml
<Picker
x:Name=“Picker1”
Style="{StaticResource PickerStyle}"
ItemsSource="{Binding CodeNumberList}"
SelectedItem="{Binding CodeNumberText}”>
<Picker.Behaviors>
<xct:EventToCommandBehavior
EventName="SelectedIndexChanged"
Command="{Binding ItemChangedCommand}"
CommandParameter="{Binding Source={x:Reference Picker1},
Path=SelectedItem}"/>
</Picker.Behaviors>
</Picker>
<Picker
x:Name=“Picker2”
Style="{StaticResource PickerStyle}"
ItemsSource="{Binding PhoneNumberList}"
SelectedItem="{Binding PhoneNumberText}”>
</Picker>
ViewModel
private ObservableCollection<string> _phumberList;
public ObservableCollection<string> PhNumberList
{
get
{
return _phumberList;
}
set
{
_phumberList = value;
RaisePropertyChanged(nameof(this.PhNumberList));
}
}
private void ItemChangedCommandHandler(string obj)
{
PopulatePhoneList();
}
private void PopulatePhoneList()
{
// tried clearing PhNumberList.Clear() and then added items, that didn't work too
//Invalid cast exception thrown in below line
PhNumberList = new ObservableCollection<string>();
foreach (var item in CurrentUser?.InformationDetailItems)
{
PhNumberList.Add (item.PhoneNumber);
}
}
public On NavigatedTo(){
// populate default pickerList
PopulatePhoneList();
}
Exception :
//Invalid cast exception thrown in below line
PhNumberList = new ObservableCollection();

Removing this part of the code should resolve the problem:
<xct:EventToCommandBehavior
EventName="SelectedIndexChanged"
Command="{Binding ItemChangedCommand}"
CommandParameter="{Binding Source={x:Reference Picker1},
Path=SelectedItem}"/>
This can be done in many other ways, like using the CodeNumberText property to handle it. As it is likely a bug in that open source component you can submit the bug to their GitHub or fix it yourself.
What I'm trying to do is to add automatic vertical scroll when expanding the editorwindow too much to the bottom :
If in the screenshot for example this is the original editorwindow size :
When clicking for example the Conversations and collapsing it then I want to make it with a vertical scroll :
I can keep stretching down the window with the mouse but I want to use scroll in that case instead :
using System.Collections;
using System.Collections.Generic;
using UnityEditor;
using UnityEditorInternal;
using UnityEngine;
public class ConversationsEditorWindow : EditorWindow
{
[MenuItem("Window/Editor Window Test")]
static void Init()
{
// Get existing open window or if none, make a new one:
ConversationsEditorWindow window = (ConversationsEditorWindow)EditorWindow.GetWindow(typeof(ConversationsEditorWindow));
}
void OnGUI()
{
GameObject sel = Selection.activeGameObject;
ConversationTrigger targetComp = sel.GetComponent<ConversationTrigger>();
if (targetComp != null)
{
EditorGUILayout.BeginVertical();
var editor = Editor.CreateEditor(targetComp);
var tar = editor.targets;
editor.OnInspectorGUI();
EditorGUILayout.EndScrollView();
EditorGUILayout.EndVertical();
}
}
}
The exception message is a bit long :
The exception is on line 27 :

Stack empty message gives a clue what goes on - you are making a call to : EditorGUILayout.EndScrollView(); (trying to pop from gui stack) without calling BeginScrollView() beforehand.

You have an error in app.config file. There is a problem with the section runtime. Be sure it is declared in and has valid structure and values.
Here the Inner exception message gives the hint

How Can I solve this exception?
Call CachedImageRenderer.Init after global::Xamarin.Forms.Forms.Init(); in FinishedLaunching method present in AppDelegate.cs file of iOS project.
It clearly mention that you need to call Init method inside this. The details will be given in the github repository of FFImageLoading plugin
It is mentioned in the following link
I would like to provide a web service that lets me download certain Excel workbooks. These Excel workbooks are SpreadsheetGear objects that may be modified with data. I don't want to write them as a file and return the file. Instead, I'd like to stream them into the browser so the user gets a downloaded file.
Here is my attempt that does not work, drawn from this guide from SpreadsheetGear's site:
[System.Web.Services.WebMethod(
Description = "Returns a stream for the excel file")]
public ActionResult downloadTemplate(string excelFileName)
{
var workbook = makeSpreadsheetGearWorkbookFrom(excelFileName);
// Save workbook to an Open XML (XLSX) workbook stream.
System.IO.Stream stream = workbook.SaveToStream(
SpreadsheetGear.FileFormat.OpenXMLWorkbook);
// Reset stream's current position back to the beginning.
stream.Seek(0, System.IO.SeekOrigin.Begin);
return new FileStreamResult(stream,
"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
}
I get the following error:
The web service returned the following result:
500 - Internal Server Error
System.InvalidOperationException: There was an error generating the XML document. ---> System.InvalidOperationException: System.Web.Mvc.FileStreamResult cannot be serialized because it does not have a parameterless constructor.

How should I approach this?
Solved the problem by returning a list of bytes instead of a StreamResult, like so:
public byte[] downloadTemplate(string excelFileName)
//...
byte[] modelData = toByteArray(stream);
return modelData;
}
public byte[] toByteArray(System.IO.Stream stream)
{
using (System.IO.MemoryStream ms = new System.IO.MemoryStream())
{
stream.CopyTo(ms);
return ms.ToArray();
}
}
It is easy to put the byte array into a JObject and then into an XML Envelope.
