I want to add a string from a textbox to an array, but when I tried to add it to the array it gives me an error (Cannot convert char[] to string[]) what is it that I'm doing wrong, and is it maybe a better way to do it?
public string[] users = { "username" };
public string[] passwords = { "password" };
string[] users = textBox1.Text.ToArray();
string[] passwords= textBox2.Text.ToArray();
You want to use char array, not string array. This is because textBox1.Text returns a string type, not a string array type. Calling ToArray() on a string results in a char array type.
char[] user = textBox1.Text.ToArray();
char[] password= textBox2.Text.ToArray();
You should also consider changing string[] user and string[] password to string type instead, since I'm assuming you are only storing one username in user. If you are trying to store a collection of users, then you should name your variable correctly, such as string[] users, to not cause confusion.
user and password have been allocated as single element arrays. Arrays are immutable and cannot be appended to, so you cannot do this:
public string[] user = { "username" };
public string[] password = { "password" };
//...
user.Append(textBox1.Text);
password.Append(textBox2.Text);
But you could reallocate the user and password arrays with something like this:
public string[] user = { "username" };
public string[] password = { "password" };
//...
user = new[] { user[0], textBox1.Text };
password = new[] { password[0], textBox2.Text };
This is rather clumsy, though. You would probably be better off defining user and password as List<String>, i.e.:
public List<string> user = new List<string>() { "username" };
public List<string> password = new List<string>() { "password" };
//...
user.Add(textBox1.Text);
password.Add(textBox2.Text);
You should use char arrays instead of string array :
public string[] users = { "username" };
public string[] passwords = { "password" };
-
char[] users = textBox1.Text.ToArray();
char[] passwords= textBox2.Text.ToArray();
And instead of string arrays you can use List<string> for users and passwords.
Tip : It's better to rename your textBoxes something like txtUserName for clearify and better code.
string[] user = { textBox1.Text };but why?userandpasswordvariables just strings as it doesn't seem like you are actually using an array, just single values. Then you can just assign directly from theTextproperty.
