从字符串转换为int以实现到Dictionary

Question

I am working on a web form that takes the input of information and stores it to a dictionary, then adds it to a listbox.

newAccount.ID is set as an integer inside the Account class. And I have parsed it in the click event. However, it says "Argument 1: cannot convert from 'int' to 'string'. I am currently checking to see if the dictionary contains the account ID before adding an exception.

protected void btnAdd_Click(object sender, EventArgs e)
    {
        Account newAccount = new Account();

        newAccount.ID = int.Parse(txtID.Text);
        newAccount.Balance = double.Parse(txtBalance.Text);
        newAccount.Name = txtName.Text;

        if (myAccounts.ContainsKey(newAccount.ID))

    }

Answer 1

I am guessing your dictionary key is string not integer . First of all that is not the best, as the data you want to keep there is of type int

If you want to keep that though:

newAccount.ID.ToString();

Will do the trick.
