When using FileStream to read files in C#, you may encounter issues with garbled characters. This is typically caused by a discrepancy between the file’s encoding and the encoding used for reading. Here are some methods for solving garbled character problems:

1. Specify the correct encoding: When creating a FileStream object, you can specify the correct encoding. For example, if the file is encoded in UTF-8, you can use UTF8Encoding to read the file.

FileStream fileStream = new FileStream("path/to/file.txt", FileMode.Open, FileAccess.Read);
StreamReader streamReader = new StreamReader(fileStream, Encoding.UTF8);
string content = streamReader.ReadToEnd();

1. Use automatic detection of encoding: You can use the GetEncoding method of the Encoding class to automatically detect the encoding of a file. This can help avoid errors that manual encoding selection may cause.

FileStream fileStream = new FileStream("path/to/file.txt", FileMode.Open, FileAccess.Read);
StreamReader streamReader = new StreamReader(fileStream, Encoding.Default, true);
string content = streamReader.ReadToEnd();

1. Convert Encoding: If garbled text has been read, you can try converting the content that has been read to the correct encoding. For example, if the content read is gibberish in UTF-8 encoding, you can use the Convert method of the Encoding class to convert it to the correct encoding.

byte[] bytes = Encoding.Default.GetBytes(content);
string correctContent = Encoding.UTF8.GetString(bytes);

By following the above methods, you should be able to fix the problem of garbled characters when using FileStream to read files in C#.
