How to read files

How to read files in C#?

What are the avai开发者_StackOverflowbable methods?

Well, there's the File class.

Vague question, but on the information given and assuming text files:

string fileData = System.IO.File.ReadAllText(@"C:\path\to\your\file.txt");

However if you are reading binary files, xml files etc there are other ways.

You're looking for every single class in System.IO except for MemoryStream.
For more details, see the documentation.

I always read .txt files with System.IO.StreamReader

StreamReader file = new StreamReader(@"C:\Windows\System32\etc.txt");

And then you can read from the file with

string blah = file.ReadLine();

or

string blahblah = file.Read()

include System.IO; //The input/output class in C# .NET

//Main Class etc.
StreamReader sr = new StreamReader(string Path);
string output = sr.Read(); //output data

C# tends to be very picky with reading data so I suggest reading binary data rather than using StreamReader.

Using System.IO.StreamReader and the .ReadLine() method will work if you need a text file line by line.
