C＃解析目录路径的输出

Question

我正试图从应用程序的输出中获取路径。 这是输出样本：

如何解析输出只是＆＃34; C：\ MyDir \ Smith_Nathalie_20170428_140834479＆＃34;并重用它来告诉storescu（发送dicom文件）要查看的路径。

ex：Storesu 106 + sd＆＃34; C：\ MyDir \ Smith_Nathalie_20170428_140834479＆＃34;

任何帮助都会很棒。

查看System.IO.Path.GetDirectoryName()

您可以使用正则表达式解析字符串中的文件名。对于您显示的字符串，我建议让Regex查找有关创建新子目录的消息。它看起来像这样

        string directoryName = string.Empty;
        string inputtext = @"creating new subdirectory for study: C:\MyDir\Smith_Nathalie_20170428_140834479 I: storing DICOM file: C:\MyDir\Smith_Nathalie_20170428_140834479\DXm.1.2.840.113681.2206606139.739.3355346425.685.1 I: Received Store Request: MsgID 2, (DXm) RECV: ..................................................................................... I: storing DICOM file: C:\MyDir\Smith_Nathalie_20170428_140834479\DXm.1.2.840.113681.2206606139.739.3355346425.687.1 I: Received Store Request: MsgID 3, (DXm)";

        System.Text.RegularExpressions.MatchCollection matchCol = System.Text.RegularExpressions.Regex.Matches(inputtext, @"(?<=creating new subdirectory for study: )[^\s]+(?=\s)");

        if (matchCol.Count > 0)
            directoryName = matchCol[0].Value;
