如何在C＃文本框中粘贴格式化的文本

Question

am trying to paste some emails into a large textbox with a semi-colon(;) at the end of each email but i don't want the semi-colon to be at the back of the last email. Please how can i go about this, all answers would be welcomed.

Answer 1

You can use the TrimEnd() function

string Emails = "me@email.com;metoo@email.com;";
this.textBox1.Text = Emails.TrimEnd(';');

or if it's already in your TextBox

this.textBox1.Text = this.textBox1.Text.TrimEnd(';');

Answer 2

Try this

string email = "metoo@email.com;abc@email.com;xyz@email.com;";
this.textBox1.text = email.Replace(";", string.Empty);
//to show emails in separate lines then use it in this way
this.textBox1.text = email.TrimEnd(';').Replace(";", Environment.NewLine);

Answer 3

Just remove the last char. You can do that with a substring.

Answer 4

I don't understand what do you want. But maybe this code can help you to remove the last semi-colon if it exists.

var str = "email@email.com;email2@email.com;email3@email.com;";
var length = str.Length - 1;

if (str.LastIndexOf(';') == length)
{
    str.Remove(length);
}
