字符串中不需要的转义字符

Question

App.Config文件内容：

    <?xml version="1.0" encoding="utf-8" ?>
<configuration>

    <appSettings>
        <add key="ConnectionString"
             value="Server=ADVDSQLMGA;User ID=ImporterApp;Password=!mp0rt3rApp;Database=id0405Moxy52"
             />


        <add key="DTS_PackageName"

        <add key="DTS_PackagePathAndFileName"
            value="\\computername\foldername\folder1\folder2\folder3\filename.dts"/>

        <add key="DTS_ImportWorkingPathAndFileName"
             value="\\computername\foldername\folder1\folder2\filename.txt"/>
        <add key="DTS_DestinationServerName"
             value="computername"/>
        <add key="DTS_DestinationDatabase"
             value="databasename"/>
        <add key="DTS_DestinationTable"
             value="databasename.dbo.tablename"/>
        <add key="DTS_DestinationUserName"
             value="username"/>

    </appSettings>


</configuration>

码：

            string DTS_PackageName = ConfigurationSettings.AppSettings["DTS_PackageName"];
            string DTS_PackagePathAndFileName = ConfigurationSettings.AppSettings["DTS_PackagePathAndFileName"];
            string DTS_PackageGUID = ConfigurationSettings.AppSettings["DTS_PackageGUID"];
            string DTS_ImportSourcePath = ConfigurationSettings.AppSettings["DTS_ImportSourcePath"];
            string DTS_ImportFileConnection = ConfigurationSettings.AppSettings["DTS_ImportFileConnection"];
            string DTS_ImportFileName = ConfigurationSettings.AppSettings["DTS_ImportFileName"];
            string DTS_ImportWorkingPath = ConfigurationSettings.AppSettings["DTS_ImportWorkingPath"];
            string DTS_ImportWorkingPathAndFileName = ConfigurationSettings.AppSettings["DTS_ImportWorkingPathAndFileName"];
            string DTS_DestinationServerName = ConfigurationSettings.AppSettings["DTS_DestinationServerName"];
            string DTS_DestinationDatabase = ConfigurationSettings.AppSettings["DTS_DestinationDatabase"];
            string DTS_DestinationTable = ConfigurationSettings.AppSettings["DTS_DestinationTable"];
            string DTS_DestinationUserName = ConfigurationSettings.AppSettings["DTS_DestinationUserName"];
            string DTS_DestinationPassword = ConfigurationSettings.AppSettings["DTS_DestinationPassword"];

            StringBuilder DTSArgs = new StringBuilder();

            DTSArgs.AppendFormat("/N \"{0}\" /G \"{1}\" /F \"{2}\" ",
                                        DTS_PackageName,
                                        DTS_PackageGUID,
                                        DTS_PackagePathAndFileName);            
            DTSArgs.AppendFormat(@"/A ""DestinationDatabase"":""8""=""{0}"" ", DTS_DestinationDatabase);
            DTSArgs.AppendFormat("/A \"DestinationPassword\":\"8\"=\"{0}\" ", DTS_DestinationPassword);
            DTSArgs.AppendFormat("/A \"DestinationServerName\":\"8\"=\"{0}\" ", DTS_DestinationServerName);
            DTSArgs.AppendFormat("/A \"DestinationTable\":\"8\"=\"{0}\" ", DTS_DestinationTable);
            DTSArgs.AppendFormat("/A \"DestinationUserName\":\"8\"=\"{0}\" ", DTS_DestinationUserName);
            DTSArgs.AppendFormat("/A \"ImportFileConnection\":\"8\"=\"{0}\" ", DTS_ImportFileConnection);
            DTSArgs.AppendFormat("/A \"ImportFileName\":\"8\"=\"{0}\" ", DTS_ImportFileName);
            DTSArgs.AppendFormat("/A \"ImportSourcePath\":\"8\"=\"{0}\" ", DTS_ImportSourcePath);
            DTSArgs.AppendFormat("/A \"ImportWorkingPath\":\"8\"=\"{0}\" ", DTS_ImportWorkingPath);
            DTSArgs.AppendFormat("/A \"ImportWorkingPathAndFileName\":\"8\"=\"{0}\" ", DTS_ImportWorkingPathAndFileName);
            DTSArgs.AppendFormat("/W \"0\"");

            System.Diagnostics.Process proc = new System.Diagnostics.Process();
            proc.EnableRaisingEvents = false;
            proc.StartInfo.FileName = "dtsrun ";
//**** PROBLEM IS HERE:  The DTSArgs escpaes the double-quotes and backslashes in paths with backslashes,
//**** then the dtsrun.exe doesn’t like the arguments (see string below)
            proc.StartInfo.Arguments = DTSArgs.ToString();

            proc.Start();

            proc.WaitForExit();

DTSARgs的样子：

/ N“BlockImportNEW”/ G“{C22A80D9-7613-43AF-939C-3C04AD7D848A}”/ F“\\ computername \\ foldername \\ folder1 \\ folder2 \\ folder3 \\ filename.dts”/ A“DestinationDatabase”：“8”=“DBNAME “/ A”DestinationPassword“：”8“=”password“/”DestinationServerName“：”8“=”ServerName“/”DestinationTable“：”8“=”dbname.dbo.tablename“/”DestinationUserName“： “8”=“userName”/“ImportFileConnection”：“8”=“file.txt';'';'0'”/ A“ImportFileName”：“8”=“file.txt”/ A“ImportSourcePath” ：“8”=“C：\\ BlockImport”/“ImportWorkingPath”：“8”=“\\ computername \\ foldername \\ folder1 \\ folder2”/“ImportWorkingPathAndFileName”：“8”=“\\ computername \\ foldername \\ folder1 \\ folder2 \\ file.txt“/ W”0“

proc.StartInfo.Arguments看起来像什么：

/ N \\“BlockImportNEW \\”/ G \\“{C22A80D9-7613-43AF-939C-3C04AD7D848A} \\”/ F \\“\\\\ computername \\ foldername \\ folder1 \\ folder2 \\ folder3 \\ filename.dts \\”/ A \\“DestinationDatabase \\“：\\”8 \\“= \\”DBNAME \\“/ A \\”DestinationPassword \\“：\\”8 \\“= \\”password \\“/ A \\”DestinationServerName \\“：\\”8 \\“= \\”ServerName \\“/ A \\”DestinationTable \\“：\\”8 \\“= \\”dbname.dbo.tablename \\“/ A \\”DestinationUserName \\“：\\”8 \\“= \\”userName \\“/ A \\”ImportFileConnection \\ “：\\”8 \\“= \\”file.txt';'';'0'\\“/ A \\”ImportFileName \\“：\\”8 \\“= \\”file.txt \\“/ A \\”ImportSourcePath \\ “：\\”8 \\“= \\”C：\\ BlockImport \\“/ A \\”ImportWorkingPath \\“：\\”8 \\“= \\”\\\\ computername \\ foldername \\ folder1 \\ folder2 \\“/ A \\”ImportWorkingPathAndFileName \\“ ：\\“8 \\”= \\“\\\\ computername \\ foldername \\ folder1 \\ folder2 \\ file.txt \\”/ W \\“0 \\”

执行proc.Start时，由于所有额外的反斜杠，它无法正常工作。 似乎DTSArgs stringbuilder字符串格式正确，但是当通过.ToString（）转换并存储在proc.StartInfo.Arguments中时，它会获得所有反斜杠。

我如何避免发送proc.StartInfo.Arguments所有这些额外的反斜杠？

Answer 1

我强烈怀疑他们不是真的在弦乐中。 您是否有机会使用调试器？ 它显示了字符串的转义形式。

将字符串写入控制台或类似的东西，你会看到真正的价值。

Answer 2

你使用的是逐字字符串文字吗？

即：

String c = @"C \B";

Answer 3

我确实发现它只是在调试器和即时窗口中显示转义字符。 当写入Process时，它实际上已经过格式化校正。 我创建了一个简单的批处理文件：

echo %1
pause

然后我用Process调用批处理文件而不是我试图运行的exe。 这样我就能看到实际发送的内容。 之前我的部分问题是cmd窗口关闭得太快了。

谢谢你的帮助！
