As the tittle says, I get this error ”invalid uri: the format of the uri could not be determined.” when I run my code:

Uri uri = new Uri(slct.Text);
if (DeleteFileOnServer(uri))
{
    nn.BalloonTipText = slct.Text + " has been deleted.";
    nn.ShowBalloonTip(30);
}

I don’t know why this error occurs and how to solve it. Can someone help me?

    The cause: This problem arises when the input value is different from what the application was expecting. In other words, the program received a value that was not in URI format when it was expecting a valid URI.

    Solution: You can fix this error by using UriBuilder instead.

    UriBuilder builder = new UriBuilder(slct.Text);

if (DeleteFileOnServer(builder.Uri))
{
...
}
