ReadAllText method appends file path to the application path

I am using ReadAllText method to read file contents into a string but I keep getting an exception file not found. That happened because, for some reason, ReadAllText appends file path to the application path and attempts to find it:

Additional information: Could not find a part of the path 'c:\Projects\MyApp1\MyApp1\bin\Debug\C\Test\MyFile.csv'.

string FileName ="C:\Test\MyFile.csv";
string allText = File.ReadAllText(fileName, encoding);

How can I fix this issue?

In C# you need to escape the \ character when you have enclosed it in a string that is enclosed in quotes. Escaping is needed because the \ character is treated as a way of displaying special characters in a text string. Change the code to the following:

string FileName ="C\\Test\\MyFile.csv";
string allText = File.ReadAllText(fileName, encoding);

You could also use the special @ operator to specify a verbatim string literal. That would look like the following following:

string FileName =@"C\Test\MyFile.csv";
string allText = File.ReadAllText(fileName, encoding);

Finally, You are missing the : character in your path. The code should actually look like the following:

string FileName = @"C:\Test\MyFile.csv";
string allText = File.ReadAllText(fileName, encoding);

You have a typo: C\ should be C:\. Also you need to escape your slashes:

"C:\\Test\\MyFile.csv"

or make the whole string a literal:

@"C:\Test\MyFile.csv"

Your FileName is off. First, you're missing a colon between drive name and forward slash; it should be C:\. Second, you should be properly escaping the \ character, like this: C:\\Test\\... (or, using verbatim strings, @"C:\Test\...")

You have missed : in filename, thus it looks like relative path for File.ReadAllText method, so it appends this to the path where executable file is located. Also \ symbols should be escaped in the string.

Just change it to

string FileName =@"C:\Test\MyFile.csv";
