I am trying to write a file on button click event but getting an unauthorized error when trying to do so.
Here is my code:
private void button1_Click(object sender, EventArgs e)
{
{
string path = @"c:\program files\MyTest.txt";
if (!File.Exists(path))
{
// Create a file to write to.
using (StreamWriter sw = File.CreateText(path))
{
sw.WriteLine("Hello");
}
}
// Open the file to read from.
using (StreamReader sr = File.OpenText(path))
{
string s = "";
while ((s = sr.ReadLine()) != null)
{
Console.WriteLine(s);
}
}
}
Getting the error by:
using (StreamWriter sw = File.CreateText(path))
Not sure what i am doing wrong? Could someone please help?
Thanks
By default in Windows a user or a programm started by a user can't write files to every location on a Windows pc.
Maybe try saving your file to a different location. If that doesn't cut it for you, then you may need to look into running your programm at an elevated permission level
If you just want to save a file for your application the tippical place to do so would be the AppData Folder. The tipcal way of getting its path goes somthing like this:
string path=Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)+"/MyApplicationFolder";
您应该更改路径以授权文件夹,例如:
string path=Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
