codice

//possible seclog paths 
     String seclogPath1 = @"\\\\" + target + "\\C$\\Program Files (x86)\\Symantec\\Symantec Endpoint Protection\\seclog.log"; 
     String seclogPath2 = @"\\\\" + target + "\\C$\\Program Files\\Symantec\\Symantec Endpoint Protection\\seclog.log"; 

     //if seclog exists 
     if (File.Exists(seclogPath1)) 
     { 
      //output.AppendText("file exists at " + seclogPath1); 
      //var seclogContent = File.Open(seclogPath1, FileMode.Open, FileAccess.Read, FileShare.ReadWrite); 

      Stream stream = File.OpenRead(seclogPath1); 
      StreamReader streamReader = new StreamReader(stream); 
      string str = streamReader.ReadToEnd(); 
      output.AppendText(str); 
      streamReader.Close(); 
      stream.Close(); 


     }

Answer 1

//possible seclog paths 
     String seclogPath1 = @"\\\\" + target + "\\C$\\Program Files (x86)\\Symantec\\Symantec Endpoint Protection\\seclog.log"; 
     String seclogPath2 = @"\\\\" + target + "\\C$\\Program Files\\Symantec\\Symantec Endpoint Protection\\seclog.log"; 

     //if seclog exists 
     if (File.Exists(seclogPath1)) 
     { 
      //output.AppendText("file exists at " + seclogPath1); 
      //var seclogContent = File.Open(seclogPath1, FileMode.Open, FileAccess.Read, FileShare.ReadWrite); 

      Stream stream = File.Open(seclogPath1, FileMode.Open, FileAccess.Read, FileShare.ReadWrite); 
       //File.OpenRead(seclogPath1); 
      StreamReader streamReader = new StreamReader(stream); 
      string str = streamReader.ReadToEnd(); 
      output.AppendText(str); 
      streamReader.Close(); 
      stream.Close(); 


     } 

quello che avevo da chang e

ho dovuto creare un filestream readwrite

codice originale

Stream stream = File.OpenRead(seclogPath1); 
     StreamReader streamReader = new StreamReader(stream); 

nuovo codice

Stream stream = File.Open(seclogPath1, FileMode.Open, FileAccess.Read, FileShare.ReadWrite); 
       //File.OpenRead(seclogPath1); 
      StreamReader streamReader = new StreamReader(stream); 

Answer 2

using (StreamReader sr = new StreamReader(filePath, true)) 
{ 
    sr.Close(); //This is mandatory 
    //Do your file operation 
}
