c# - 在给定的字符串中打印不可打印的字符？

Question

我有一个字符串，在 sql 中我测试过这个字符串包含不可打印的字符，但我找不到那些字符。

那么谁能建议我如何在 C# 中查找和打印那些不可打印的字符通过传递这个字符串？

I ordered a Taurus in August and it hasn't been scheduled, I was just wondering if there is something wrong with the order? Or if the queue is just long? Order Number:8028Vehicle Rep:74JTag#: 200L049Description: 2011 TAURUS FWD SELOrdered: 08-AUG- 2010VIN Assigned:VIN#:Scheduled:In Production:Produced:Invoiced:Released:Shipped:Ready:Tax Location: STATE OF MICHIGAN (20 )State Insured:USOB Status:050 - CLEAN UNSCHEDULED ORDER

当我在 notepad++ 中粘贴字符串时，它显示如下。

您可以使用 char.IsControl(c) 来测试字符是否是控制(不可打印)字符:

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