Check if Excel file exist or not in ASP.Net Web API

Hi SUJAYS,

I am working on it, I will get back to you soon.

Hi SUJAYS,

Use DirectoryInfo class.

Please refer below code.

Code

public void CheckFileExist()
{
    string folderPath = Server.MapPath("~/Files");
    DirectoryInfo directoryInfo = new DirectoryInfo(folderPath);
    FileInfo[] excels = directoryInfo.GetFiles("*.xlsx");
    string isExists= excels.Length > 0 ? "File exists." : "File does not exist.";
}

Output

File exists.
