我做错了吗？请问为什么我不能打开两个pdfs文件保存？
至于MemoryStream，它会保存到我的目录 - ＆gt;从Chrome下载文件夹 对于FileStream，它将保存到我的代码中指定的FilePath。
请欣赏任何帮助。谢谢。
代码：
protected void BTN_Assign_Click(object sender, EventArgs e)
{
//String id = DDL_PatientID.SelectedItem.ToString();
String id = TB_PatientID.Text;
String name = TB_PatientName.Text;

String block = TB_Block.Text;
String level = TB_Level.Text;
String staffId = DDL_StaffID.SelectedItem.ToString();

String dtAssign = dt.ToString("dd MMM yyyy h:mm tt");
int result = 0;
//Assigning bed (In Beds Table)
/*BedsBLL add = new BedsBLL();
result = add.assignBed(bedID, id, name, classType, block, level, staffId, dtAssign);*/

尝试将.Close（）放在.CopyTo（）之前：
pdfDocument.Close();
ms.Position = 0;
ms.CopyTo(fs);
答案 1 :(得分：0)
我让它在两个地方保存......
Chrome和指定文件夹的默认下载文件夹。
编辑的代码：
pdfDocument.Close();
//ms.Position = 0;
//ms.CopyTo(fs);
//fs.CopyTo(ms);
byte[] bytes = ms.ToArray();
using (FileStream fs = new FileStream(fileName, FileMode.Create))
{
ms.Position = 0;
ms.CopyTo(fs);
}
