将字符句点替换为莫尔斯语代码会使TextBox变得混乱

我正在尝试将所有字符替换为他们的莫尔斯代码等价物。 我使用了textBlock.Text.Replace（）方法来实现这一点，它工作正常，直到我达到句点字符。 当我尝试用“。-.- .-”替换它时，它工作正常但是现在所有其他角色都搞砸了。 在人物角色之前，一切都很好。

这是代码

namespace PivotApp1 { public partial class Textmorse : PhoneApplicationPage { public string[] aakkoset = { "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V","W", "X", "Y", "Z", "Ä", "Ö", "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "?", ":", ",", "@", "/", "=", " ", "."}; public string[] morse = { ".- ", "-...
