Converting json to MemoryStream and back breaks the json

For context, I have the following JSON (most of the stuff omitted for brevity):

{"schemaId":"azureMonitorCommonAlertSchema","data":{...}}

{"schemaId":"azureMonitorCommonAlertSchema","data":{...}}

After I convert it to a

MemoryStream

MemoryStream

and back to string, it surrounds the string with quotation marks and re-escapes the already-escaped characters.

Method used to convert to

MemoryStream

MemoryStream

internal static MemoryStream CreateMemoryStream(this string data)
{
  byte[] byteArray = Encoding.UTF8.GetBytes(data);
  MemoryStream stream = new(byteArray) { Position = 0 };
  return stream;
}

internal static MemoryStream CreateMemoryStream(this string data)
{
  byte[] byteArray = Encoding.UTF8.GetBytes(data);
  MemoryStream stream = new(byteArray) { Position = 0 };
  return stream;
}

I also tried using a
StreamWriter
StreamWriter
approach, but to no avail.

The snippet of code that converts the

MemoryStream

MemoryStream

back to

string

string

 using StreamReader reader = new(ms, encoding: System.Text.Encoding.UTF8, leaveOpen: true);
 string result = await reader.ReadToEndAsync();

 using StreamReader reader = new(ms, encoding: System.Text.Encoding.UTF8, leaveOpen: true);
 string result = await reader.ReadToEndAsync();

It results in the following broken JSON:

"{\"schemaId\":\"azureMonitorCommonAlertSchema\",\"data\":{...}}"

"{\"schemaId\":\"azureMonitorCommonAlertSchema\",\"data\":{...}}"

I can't pinpoint exactly why this is happening, I guess it has to do with the fact that when it reads it back to a

string

string

, because the content is already a "

string

string

", it escapes the already-escaped quotes and surrounds it with the quotemarks. I don't know how to avoid this behaviour tho.

Edit: change wording
