使用C＃創建PDF

Question

當我嘗試將二進制文件轉換爲PDF時，pdf已損壞。

byte[] stream = presenter.getItemTable(); 

Response.Clear(); 
Response.ClearHeaders(); 
Response.ContentType = "application/pdf"; 
Response.AddHeader ("Content-Disposition", "attachment; filename=PressRelease.pdf"); 
Response.BinaryWrite(stream);//Entities.EDRSearchResult.ByteStream); 
Response.Flush(); 
Response.End(); 

但是，當我將相同的二進制轉換爲Excel它工作正常，可以打開沒有任何錯誤。

byte[] stream = presenter.getItemTable(); 
Response.Clear(); 
Response.ClearHeaders(); 
Response.ContentType = "application/vnd.openxmlformats - officedocument.spreadsheetml.sheet"; 
Response.AddHeader("content-disposition","attachment;filename=DataTable.xls"); 
Response.BinaryWrite(stream); 
Response.Flush(); 
Response.End(); 

請幫幫我。

Answer 1

當您嘗試將二進制文件轉換爲PDF在這種情況下，你寫

Response.AddHeader ("Content-Disposition", "attachment; filename=PressRelease.pdf"); 

嘗試

Response.AddHeader ("content-disposition", "attachment; filename=PressRelease.pdf");
