Depending on the answer to this https://github.com/OData/odata.net/pull/3190/files#r1978721142, is this scenario possible?

I think that the first thing we should check is string.IsNullOrWhiteSpace at the beginning of this method

This is after removing the first and last brackets and trimming the spaces before and after content. I also don't think at this point we can have null or empty whitespaces without the brackets. So the check for isNullOrWhiteSpace will always return false.

{
return true;
}

bool isEmptyOrHasOnlySpaces = true;
bool isCharinsideQuotes = false;
char quoteChar = '\0';
Span<char> buffer = stackalloc char[content.Length];
int bufferIndex = 0;

for (int i = 0; i < content.Length; i++)
{
char c = content[i];

if (isCharinsideQuotes)
{
if (c == quoteChar)
{
isCharinsideQuotes = false;
}
buffer[bufferIndex++] = c;
}
else
{
if (c == '"' || c == '\'')
{
isCharinsideQuotes = true;
quoteChar = c;
buffer[bufferIndex++] = c;
}
else if (c == ',')
{
string item = new string(buffer[..bufferIndex]).Trim().Trim('\'', '"');

if (!string.IsNullOrWhiteSpace(item))
{
isEmptyOrHasOnlySpaces = false;
break;
}
bufferIndex = 0;
}
else
{
buffer[bufferIndex++] = c;
}
}
}

if (bufferIndex > 0)
{
string lastItem = new string(buffer[..bufferIndex]).Trim().Trim('\'', '"');

if (!string.IsNullOrWhiteSpace(lastItem))
{
isEmptyOrHasOnlySpaces = false;
}
}

return isEmptyOrHasOnlySpaces;
}
}
}
