Read a text file to string

Dinesh Santhalingam

9yAsked Jan 19, 2017, 7:47 AM899Visual Basic .NET

I read a text from a text file and stores in an Array.

string[] lines = System.IO.File.ReadAllLines(@"D:\as\testingfile");

Here I stores the text file contents into the String array.The text file contains some empty lines .I want to skip the line and copy the content from the text file to string.Can anyone help me to solve this?

For array there is no Replace method exists. So either you can again write or else use string.
thanks.

Why we again write the file.Is it possible to remove empty line while reading?
Using this we can skip the empty lines.But it is not an array it is string.
string data2 = File.ReadAllText(@"D:\de\inputprocessing").Replace("\r\n\r\n","\r\n");
Using array{};
string [] data2 = File.ReadAllText(@"D:\de\inputprocessing").Replace("\r\n\r\n","\r\n"); //error populationg.

Hi,

You can do like this,

File.WriteAllLines(path, File.ReadAllLines(path).Where(l => !string.IsNullOrWhiteSpace(l)));

thanks.
