写入文件后打开文件

Question

I have a small app that writes to an excel file.

I would like for the program to immediately open the file after it has finished saving it.

How to go about doing just that?

Using Epplus to handle the excel.

Answer 1

if u just want to open file in C# u can just import

using System.Diagnostics;

then u can run process for "xlsx" file with Process.Start(string path);

class Program
{
    static void Main()
    {
        Process.Start(@"C:\your.xlsx");
    }
}

Answer 2

Process process = new Process();

 process.StartInfo.FileName = "excel.exe";
 process.StartInfo.Arguments = "myfyle.xls";
 process.Start();
