The following line of code is causing me an Exception
plug.Instance.AddDocuments(new Int32[] { val_pid }, val_ptype, val_doccat, val_subcat, val_doctype, val_notes, val_summary, SummaryAppendOptions.None, val_docStatus, new String[] { PDFFile })
And this is the exception detail.
System.Exception was caught
Message=Object reference not set to an instance of an object. - Error when trying to save document
Source=SimsBridge
StackTrace:

InnerException:
I'm not looking for a solution to the actual exception.
My question is, does the stacktrace point to which part of the method doesn't have a reference set? Or is stacktrace just to trace to where the method is called?
The stack trace shows you the call stack when an exception is thrown. From what you've provided you can only deduce that an exception was thrown from AddDocuments. Any of the reference type parameters passed in could be null. The best way to pinpoint the problems is to set a breakpoint and than inspect the values.
Your stack trace means that either SimsBridge or SimsBridge.Bridge is null.
The message is telling you that somewhere in AddDocuments a null reference exception was thrown. It could be one of the parameters or a member.

Using PuppeteerSharp, I am attempting to get the performance.timeOrigin value using the C# code below:
JToken performanceTimeOriginString = await _page.EvaluateFunctionAsync("JSON.stringify(performance.timeOrigin);").ConfigureAwait(false);
I have verified that this works in a JavaScript console:
However, when I run the above PuppeteerSharp code, I get the following exception:
System.AggregateException: One or more errors occurred. (Evaluation failed: SyntaxError: Unexpected token ';') ---> PuppeteerSharp.EvaluationFailedException: Evaluation failed: SyntaxError: Unexpected token ';'

at PuppeteerSharp.DOMWorld.EvaluateFunctionAsync[T](String script, Object[] args)

It was telling me to remove the semicolon (very odd), so I tried that but then got the below exception.
System.AggregateException: One or more errors occurred. (Protocol error (Runtime.callFunctionOn): Given expression does not evaluate to a function) ---> PuppeteerSharp.EvaluationFailedException: Protocol error (Runtime.callFunctionOn): Given expression does not evaluate to a function ---> PuppeteerSharp.MessageException: Protocol error (Runtime.callFunctionOn): Given expression does not evaluate to a function

--- End of inner exception stack trace ---
How can I use PuppeteerSharp to get the value of performance.timeOrigin?
You should use EvaluateExpressionAsync.
_page.EvaluateExpressionAsync("JSON.stringify(performance.timeOrigin)").ConfigureAwait(false);
Sorry if the title may be misleading, but I have created a decoder in c#, but how do I use the function on (save.dat (the game save)) it needs to be loaded in a byte array.
Code for the decoder: https://del.dog/sorononami
Sorry I'm a starter in c#.
I have tried but I got this error:
Unhandled Exception: System.TypeInitializationException: The type initializer for 'ConsoleApp8.Program' threw an exception. ---> System.NullReferenceException: Object reference not set to an instance of an object.

Looks like I am not doing it correctly
I don't think it's anything wrong with your decoder. The error message suggests you have a parameter in the constructor to your program, which the runtime doesn't know how to resolve.
Try removing any parameters from the main entry point into your programs (except string[] args).
Alternatively, post the code from your program's entry point.
I am working on a unit testing for a function in a form call Tester.cs, below is the error:

On line 35 is a code, which basically retrieve value from configuration file and convert it to integer:
private static int _part = int.Parse(ConfigurationManager.AppSettings["Part"]);
What is the error? Thank you.
The likelyhood is that ConfigurationManager.AppSettings["Part"] is returning null. Hense the parse exception.
Does your unit test project have the app setting defined in its configuration?
You should copy your app.config (or web.config) file into test project. Otherwise test project can't find it. Remember config is related to host process, not to the dll itself.
Put the break point in line 35, something there is null which should not be...Null value can not be parsed into INT....
Be ensure that the config file is placed correctly at the directory from which you're running the application
I have written a simple wpf application for binding data in datagrid. It throws error while running at following line.
string ConString = System.Configuration.ConfigurationManager
.ConnectionStrings["ConString"].ToString();
Exception shows: Exception has been thrown by the target of an invocation."
InnerException:{"Object reference not set to an instance of an object."}
Probably System.Configuration.ConfigurationManager.ConnectionStrings["ConString"] is NULL or
System.Configuration.ConfigurationManager.ConnectionStrings is NULL.
I'm trying to break my sharepoint project into a few smaller projects.
I could easily move utility files in different project.
However i encountered a problem when i moved custom-fields.
If i move custom-field from ProjectA to ProjectB and set ProjectA to reference ProjectB's DLL, building and deploying work fine. However, when program reference custom-field from SPListItem, it will throw System.ArgumentOutOfRangeException.
e.g.
SPListItem item = splist.GetItemById(id);<br>
CustomFieldValue custom = item["Custom"] // Error occurs here
Also, if i call AddFieldAsXml to define above custom-field, i get same error.
can anyone help me solve this problem?
thank you in advance...

but i don't know why i get this error.
I solved the problem...
I didn't copy the fldtypes_xxxx.xml information.
so when the code try to read some information from the xml, exception is thrown...
