当前上下文中不存在名称"toAdresses"

错误如下: CS0103: The name 'toAdresses' does not exist in the current context

在以下代码中:

public bool myFunction()
    {
        string toAddress;

        toAddress = "paul@gmail.com,jhon@gmail.com";        // for testing

        int firstCharacter = toAddress.IndexOf(',');

        if (firstCharacter != -1)
        {
            string[] toAdresses = toAddress.Split(',');
        }
        else 
        { 
            string[] toAdresses = new string[]{toAddress};
        }

        for (int i = 0; i < toAdresses.Length; i++)     // here is the error with toAdresses.Length
        {
            // do this
        }
    }

谢谢你的帮助!
