Problem With Using Elements Of An String

i have this code for example:

string i = "100";

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

i[1] is the second character in the string, as arrays in c# are zero-based.

You're comparing a string to an integer.

Try if (i[1] == '0').

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");
}

i[1] is a char of '0' (Unicode U+0030), which is different than (int) 0.
