An array of strings compiles.
tn.Split(new string[]{"one","two"}, 2, StringSplitOptions.RemoveEmptyEntries);

Solution 4

Hi,

First of all I would like to know the textBox1.Text.
Does above has text contains "@" character?

Second is that how many "@" in textBox1.Text?

Executing these code:

C#

string mytext = textBox1.Text;
string[] parts = mytext.Split(mytext,"@");
textBox2.Text = parts[1];

Scenario 1
mytext contains 1 "@" character.

C#

textBox2.Text = parts[1];  // Error  invalid arguments

Because index start at 0

Try to execute:

C#

textBox2.Text = parts[0];  // No error valid arguments

Array index start at 0.

Please vote if could help...

Solution 3

you can do as below. i have replace double quote to single quote because split function is not support string as a parameters, either we have to pass char or char array. if we write double quote, it become a string

C#

string[] parts = mytext.Split('@');
