後臺上傳
string localFileName = null; string fileName = Guid.NewGuid().ToString("N") + Path.GetExtension(file.FileName); string location = Path.Combine(""); //上傳到的路徑 using (FileStream fs = new FileStream(location, FileMode.Create)) { await file.CopyToAsync(fs); fs.Close(); localFileName = fs.Name; } return await SetupFromMSProjectMaterials(projectId, localFileName);
後臺解析使用NPOI
