从一行文本中获取特定数据

Question

我需要从下面的文本行中提取以下数据（粗体），并将其放入数据网格中;

PERS tooldata t_rrt_ja03579：= [TRUE，[[-39.643，-0.001,1025.49]，[0.382684，-0.000130001，-0.923889,0.000120001]]，[200.9，[ - 88.1 - 12.6,359.7]，[1,0,0,0]，29.347,50.927,18.261]];

这行是从文件中读取的。我设法修剪了这条线，所以它摆脱了“PERS tooldata”和空格，并且留下了工具名称。我将它绑定到代码中其他地方的datagrid中的数据，这些代码完成了第1步。

我的问题是我怎样才能提取单独的粗体的值，并把它们放在双倍的数据声明？第一块数值（-39.643，-0.001,1025.49）是X，Y，Z坐标值，第二块（0.382684，-0.000130001，-0.923889,0.000120001）是Q1，Q2，Q3，Q4。

下面是我如何做名

private void AutoFillToolData(object sender, RoutedEventArgs e) 
    { 
     // Gives user option to auto populate datagrid 
     var AutoFillToolResult = MessageBox.Show("Do you want to auto populate fields?", "Tool Data", MessageBoxButton.YesNo); 
     if (AutoFillToolResult == MessageBoxResult.Yes) 
     { 
      // User directs application to the specified file 
      System.Windows.Forms.FolderBrowserDialog folderBrowser = new System.Windows.Forms.FolderBrowserDialog(); 
      if (folderBrowser.ShowDialog() == System.Windows.Forms.DialogResult.OK) 
      { 
       // Application looks for specific file and removes unwanted data 
       string robotBackupPath = folderBrowser.SelectedPath; 
       string allDataPath = robotBackupPath + @"\RAPID\TASK1\SYSMOD\ALL_DATA.sys"; 
       string[] tLines = File.ReadAllLines(allDataPath); 
       List<string> toolDataLines = new List<string>(); 
       foreach (string tLine in tLines) 
       { 
        if (tLine.Contains("PERS tooldata") && !tLine.StartsWith("!")) 
        { 
         if (tLine.Contains("tToolChanger")) continue; 
         if (tLine.Contains("tPointer")) continue; 
         if (tLine.Contains("tHome")) continue; 
         toolDataLines.Add(tLine); 
        } 
       } 

       foreach (string line in toolDataLines) 
       { 
        // Gets the name of the tool 
        ToolData toolData = GetToolNameFromLine(line); 

        // Puts the tool name in the DataGrid 
        TCPData.Add(toolData); 
       } 
      } 
     } 
    } 

    private ToolData GetToolNameFromLine(string line) 
    { 
     // Removes white space at the beggining of line in txt file 
     ToolData tooldata = new ToolData(); 
     string[] spaceSplit = line.Trim().Split(' '); 
     string values = spaceSplit[2]; 

     // Gets Tool Name 
     int colonLocation = values.IndexOf(":"); 
     tooldata.ToolName = values.Substring(0, colonLocation); 
     return tooldata; 
    } 

Answer 1

如果所有你必须遵循相同的模式样本，似乎并提取这些值并不难：

//First we get all the string after the := 
string tooldata = line.Substring(data.IndexOf(":=") + 2) ; 

//Split the string by [   
string[] tooldataArray = tooldata.Split(new char[] { '[' }, StringSplitOptions.RemoveEmptyEntries); 
//the second and the third strings are what we are interested in 
string xyzValue = tooldataArray[1].Replace(']' ,' '); 
string Q1234value = tooldataArray[2].Replace(']', ' '); 

如果之后你想要获得个别参数，只需要分开,就行。

这将提取所有你想要的值的double阵列：

string tooldata = data.Substring(data.IndexOf(":=") + 2) ; 

string[] tooldataArray = tooldata.Split(new char[] { '[' }, StringSplitOptions.RemoveEmptyEntries); 
double[] xyzValue = tooldataArray[1].Replace(']' ,' ') 
        .Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries) 
        .Select(s => double.Parse(s, CultureInfo.InvariantCulture)) 
        .ToArray(); 
double[] Q1234value = tooldataArray[2].Replace(']', ' ') 
        .Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries) 
        .Select(s => double.Parse(s, CultureInfo.InvariantCulture)) 
        .ToArray();
