         if (line.Contains(searchstring))
          {
               if (line.Contains(searchfromdate)) //|| line.Contains(searchtodate)) 
                  {
                        sb.AppendLine(line.ToString());
                        counter++;

ResultTextBox.Text = sb.ToString();
CountLabel.Text = counter.ToString();

2 个解决方案

#1

To access files on a server you need 2 things

要访问服务器上的文件，您需要两件事

• Make sure your are using aa user that hass permission to access the file

  确保您使用的是具有访问该文件权限的用户

• Set the server address path as \servername1\Folder\file.txt

  将服务器地址路径设置为\ servername1 \ Folder \ file.txt

so using your code you would have to have something like

所以使用你的代码你必须有类似的东西

string line;
string path = @"\\server1\TextFolder\Text.txt";
StringBuilder sb = new StringBuilder();
int counter = 0;

using (StreamReader file = new StreamReader(path))
{
  while ((line = file.ReadLine()) != null)
      {
         if (line.Contains(searchstring))
          {
               if (line.Contains(searchfromdate)) //|| line.Contains(searchtodate)) 
                  {
                        sb.AppendLine(line.ToString());
                        counter++;
                  }
          }
      }
}

ResultTextBox.Text = sb.ToString();
CountLabel.Text = counter.ToString();

1. you need to Share the folder in server machine and provide Read permission to the users who want to access it from remotly.

1.您需要在服务器计算机*享该文件夹，并为希望从远程访问它的用户提供“读取”权限。

2. Get the IPAddress or Hostname of the Server machine so that you can access the shared folders.

2.获取服务器计算机的IPAddress或主机名，以便可以访问共享文件夹。

3. Now prepare the filepath as below:

3.现在准备文件路径如下：

Example: if ServerName is MyServer123 and FolderName is MyFolder FileName is myFile.txt

示例：如果ServerName是MyServer123而FolderName是MyFolder，则FileName是myFile.txt

your path should be "\\MyServer123\MyFolder\MyFile.txt"

你的路径应该是“\\ MyServer123 \ MyFolder \ MyFile.txt”

Complete Code:

完整代码：

StringBuilder sb = new StringBuilder();
int counter = 0;
String path=@"\\MyServer123\MyFolder\MyFile.txt";
foreach(var line in File.ReadLines(path))
{
  if (line.Contains(searchstring) && (line.Contains(searchfromdate)))
  {
    sb.AppendLine(line);
    counter++;
  }
}
ResultTextBox.Text = sb.ToString();
CountLabel.Text = counter.ToString();
