我有一个字符串，在SQL中我测试过这个字符串包含非打印字符，但我无法找到它们的。

推荐答案

您可以使用 char.IsControl（C）来测试一个字符是否是一个控制（非可打印）字符或不：

You can use char.IsControl(c) to test whether a character is a control (non-printable) character or not:

foreach (var c in str)
{
    if (char.IsControl(c))
    {
        Console.WriteLine("Found control character: {0}", (int)c);
    }
}
