How to use SarifLog.Save(outputFilePath) to output a sarif file in SARIF v2.1.0 format?

I used sarif sdk to read a sample sarif file (sarif-tutorials\samples\Baseline.sarif) and save it to another one as following simple code :
SarifLog sarifLog = SarifLog.Load(@"Baseline.sarif");
sarifLog.Save(@"mysarif.sarif");

But the result file "mysarif.sarif" that I got is not the same as the original one.

Did I missing something else?Thank you for your information.

I think you could use this example, except remove the ContractResolver assignment:

sarif-sdk/docs/how-to.md

Lines 20 to 29 in 025f64c

    
           var settings = new JsonSerializerSettings() 
        
           { 
        
               ContractResolver = SarifContractResolverVersionOne.Instance, 
        
               Formatting = Formatting.Indented 
        
           }; 
        
           SarifLogVersionOne log = ... ; 
        
           sarifText = JsonConvert.SerializeObject(log, settings); 
        
           File.WriteAllText(outputFilePath, sarifText);

Alternatively, call SarifLog.Save(Stream) with a MemoryStream and then reformat that using JSON reader and writer classes.

(Why does SarifLog define public void Save(StreamWriter streamWriter)? It would be more useful to define public void Save(TextWriter textWriter), which would allow StringWriter too.)

Thank you for your suggestion.
After load sarif contents by SarifLog.Load, I used Json.Net to serialize the contents then write to file as your advice.
The result i got is as same as the original one.

	var settings = new JsonSerializerSettings()
	{
	ContractResolver = SarifContractResolverVersionOne.Instance,
	Formatting = Formatting.Indented
	};

	SarifLogVersionOne log = ... ;

	sarifText = JsonConvert.SerializeObject(log, settings);
	File.WriteAllText(outputFilePath, sarifText);
