Good morning,
I need to open a .txt file exclusively so that if another program tries to read, it receives a warning preventing it from opening.
The file I'm going to read is a file that contains data in a specific layout and when opening I need to read line by line.
Thank you!
Simple, you can use StreamReader. While not executing the Close () method, the file will be locked by the operating system.
Code:
using (StreamReader rd = new StreamReader("arquivo.txt",Encoding.Default))
{
string linha = null;
while ( (linha = rd.ReadLine()) != null)
{
//sua linha = linha
}
rd.Close();
}
Within% w / w% the variable% w /% represents each line of the file.
