Issue with removing symbols from a string

Question

I'd like to remove every "\\n" symbol from every single array element. But after using this code nothing happens;

string[] Words = TextBox.Text.Split(' ');

for (int i = 0; i < Words.Length; i++)
{
    Words[i].Replace("\n", "");
}

What's wrong here?

Answer 1

String.Replace returns a new string; it doesn't affect the original. You need to use

Words[i] = Words[i].Replace("\n", "");

Answer 2

尝试这个

TextBox.Text = TextBox.Text.Replace(Environment.NewLine, string.Empty);

Answer 3

尝试Words[i] = Words[i].Replace("\\n", "");

Answer 4

Strings are immutable. That means that any operation on a string that has already had it's value set, returns a new string and does not change the original string.

As others have said, you need to assign the result of your replace operation to a new string.
