C#将结果转换为新行

我有一个文本加密机，我可以在其中添加我想要加密的行到textbox，输出将在另一个textbox中。 当我现在尝试加密它时，我会得到所有行一起加密的结果。我想让输入框中的一行变成输出框中的一行。我当前的代码：

var simple = new Simple3Des("randompass");
txtEncrypted.Text = simple.Encode(txtInput.Text);

当前结果：

输入：

random:random
random:random
random:random

random:random
random:random
random:random

random:random
random:random

random:random
random:random

输出：

我想要的结果：

输入：

更新：

1。使用此选项：

var simple = new Simple3Des("randompass");
txtEncrypted.Text = simple.Encode(txtInput.Text);

我得到的结果是：

输入：

random:random
random:random
random:random

random:random
random:random
random:random

random:random
random:random

random:random
random:random

结果:

fuxvDhEy+pUnPREKodMsErFusuSLRZHxtKSNhp1XYgQMmzXSeMKN0dGLn+EQuuCAaWvC4E6mokw=

fuxvDhEy+pUnPREKodMsErFusuSLRZHxtKSNhp1XYgQMmzXSeMKN0dGLn+EQuuCAaWvC4E6mokw=

2。使用答案中的代码：

var simple = new Simple3Des("randompass");
var input = txtAccount.Text.Split(new[] {Environment.NewLine}, StringSplitOptions.RemoveEmptyEntries);

var output = new StringBuilder();

foreach (var i in input)
    output.AppendLine(simple.Encode(i));

txtEncrypted.Text = output.ToString();

var simple = new Simple3Des("randompass");
var input = txtAccount.Text.Split(new[] {Environment.NewLine}, StringSplitOptions.RemoveEmptyEntries);

var output = new StringBuilder();

foreach (var i in input)
    output.AppendLine(simple.Encode(i));

txtEncrypted.Text = output.ToString();

我得到的结果

输入：

random:random
random:random
random:random

random:random
random:random
random:random

random:random
random:random

random:random
random:random

结果:

fuxvDhEy+pUnPREKodMsErFusuSLRZHxtKSNhp1XYgQMmzXSeMKN0dGLn+EQuuCAaWvC4E6mokw=

fuxvDhEy+pUnPREKodMsErFusuSLRZHxtKSNhp1XYgQMmzXSeMKN0dGLn+EQuuCAaWvC4E6mokw=

这两种情况下的结果实际上是相同的

假设输入文本框中的每一行文本都可以单独加密，您可以在换行符上拆分，一次加密每一行，然后显示结果：
