as the title says I try to get an info from an array in foreach. This is for Microsoft form application! What I try so far is :
private void tabPage1_Click(object sender, EventArgs e)
{
string[] names = new string[] { "Matt", "Joanne", "Robert" };
foreach (string element in names)
{
label3.Text = (string)element[1];
}
}
What am I doing wrong?
(string)element[1] gets the second character in string element and then converts that to a string. (It's equivalent to element.Substring(1, 1).)
What you probably want to do is just use element: label3.Text = element;
However, there is still an issue here, which is that label3.Text will end up being the last element of names. I doubt that this is what you want.
element[1] is a char, as element is one of the strings from your names array.
So the error message is correct, you cannot cast a char to a string.
Perhaps you meant this:
label3.Text = element;
All you need to change is:
private void tabPage1_Click(object sender, EventArgs e)
{
string[] names = new string[] { "Matt", "Joanne", "Robert" };
foreach (string element in names)
{
label3.Text = element;
}
}
This will update the label to show Matt, then Joanne, then Robert.
If you would like to do it that way, you can use a for loop
for(int i = 0; i <= 2; i++)
{
label3.Text = names[i];
}
This line
label3.Text = (string)element[1];
means display the first character of each element of your string array names. Get the first character, cast it to string and assign it to label text. Explicit casting from char to string is not allowed and that is why you get error.
Cannot convert type 'char' to 'string'
You can fix that by using:
label3.Text = element;
But this will lead to another issue, You will get end up with the last value in your array in the Label.
If you want to show all the values in an array separated by some delimiter like comma then use :
private void tabPage1_Click(object sender, EventArgs e)
{
string[] names = new string[] { "Matt", "Joanne", "Robert" };
label3.Text = string.Join(",", names);
}
