从C＃执行sql查询时更改文件路径

Question

I have a sql database where i am string filepath and file name of some files. I am using Visual Studio 2008 as IDE and SQL Server 2005 for development.

If I am trying to execute a SQL query to get filepath it returns correct result. But when I am executing SQL query from windows application in c#, it is returning Filepath in which all \\ are changed to // .

Here is the SQL query I executed from SQL Server Management Studio:

select FilePath FROM dbo.[tbl_name] WHERE SerialNo = 2;

It results in FilePath being C:\\Program Files\\Test\\Mydoc.pdf

But when I am trying through C# windows forms code as mentioned below. I am getting a wrong value for FilePath : C://Program Files//Test//Mydoc.pdf

try
{
     using (connection = new SqlConnection(connectionString))
     {
          connection.Open();
          using (SqlCommand command = new SqlCommand("SELECT FilePath FROM dbo.[tbl_name] WHERE SerialNo LIKE @Sno", connection))
          {
              command.Parameters.Add(new SqlParameter("Sno", Serial));
              FiletoOpen = command.ExecuteScalar().ToString();
              Process.Start(FiletoOpen );
          }
      }
}
catch (Exception ex)
{
     MessageBox.Show(ex.ToString(), "Exception has occured!", MessageBoxButtons.OK);
}
finally
{
      connection.Close ();
}

What may be the problem?

I guess you are seeing this path in your debugger. Debugger is just escaping the path and nothing else . If you write it somewhere, like console, you will get the original path (with single backslashes).
