Question

i have this code for example:

string i = "100";

if(i[1]==0)
{
    MessageBox.Show("ok");
}

and I thought I should get “ok” but it doesnt work. What is i[1] here?

Answer 1

Your comparison is using the wrong type. When you use an indexer with a string, the result is a char. Your if statement is using an int. You need to change your code to:

if(i[1] == '0')
{
    MessageBox.Show("Ok");
}
