I have the following piece of code which opens a text file and reads all the lines in the file and storing it into a string array.
Which then checks if the string is present in the array. However the issue I'm facing is that whenever a string is found, it always shows "there is a match" as well as "there is no match". Any idea how to fix this?
check this code:
using (StreamReader sr = File.OpenText(path))
{
string[] lines = File.ReadAllLines(path);
for (int x = 0; x < lines.Length - 1; x++)
{
if (domain == lines[x])
{
sr.Close();
MessageBox.Show("there is a match");
}
}
if (sr != null)
{
sr.Close();
MessageBox.Show("there is no match");
}
}
Sounds overly complex, no reason to check by line or anything if you want to know if a string is present in a file. You can replace all of your code simply with :
if(File.ReadAllText(path).Contains(domain))
{
MessageBox.Show("There is a match");
}
