Using StreamReader to get text

I am tring to get the contents of a text file using StreamReader.  Not sure if it is considered UniCode or ASCII.
I tried changing the Encoding to various things (UniCode, <default>, ASCII)  it just returns a number like 126 or 1509.  My StreamWriter Function works perfect (i.e.  A File that says "Hello World" is 12 Bytes), but the StreamReader doesn't

I just a simple Function to give the contents of a File into a String,
strMyText = ReadFile("f:\test.txt")

Thank You Very Much in Advance
 


Function ReadFile(ByVal FullLocation As String) As String
        Dim srFile As StreamReader
        srFile = New StreamReader(FullLocation)
        ReadFile = srFile.Read()
        srFile.Close()
    End Function

you can use:

string text = ReadAllText(@"f:\text.txt");

ReadAllText  humm???

Function ReadFile(ByVal FullLocation As String) As String
        Dim srFile As StreamReader
        srFile = New StreamReader(FullLocation)
        ReadFile = srFile.ReadAllText()
        srFile.Close()
End Function
Is this right?

I also have another question pending if you want to answer it:)

no need, ReadAllText replaces all your code.
BTW, remove the @, it is needed just in C#, not vb.net

It doesn't like ReadAllText as a VB.NET Function???

ReadFile = ReadAllText("f:\text.txt")

oops, sorry, it is:

ReadFile = File.ReadAlText("f:\text.txt")

or

ReadFile = System.IO.File.ReadAlText("f:\text.txt")

if you have Imports System.IO, then you need:
ReadFile = File.ReadAlText("f:\text.txt")
