字符串到字节数组值 [英] String to byte array value

问题描述

我有一个数据库字段varbinary，我在c＃中检索并存储在列表中。单击按钮时，我传递一个authnum值并将值存储在val中。

 var authval =来自authlt in lstarray 
其中authlt.AuthNum == authnum 
选择authlt.authLetter; 

i尝试打开pdf通过将authval提供给二进制编写器，以便在其中显示pdf的新窗口。但它不起作用。它要求我给出一个字节数组，我无法从字符串值中获取。



是否有办法将所有字符串字符串char复制到字节数组???

从字符串中显示pdf的任何其他方式？







任何帮助表示赞赏。

解决方案

尝试：

  byte  [] array = Encoding.UTF8.GetBytes（  Hello world！）; 

hi,

I have a database field varbinary which I am retrieving in c# and storing in a list. on button click I am passing a authnum value and storing the value in val.

var authval = from authlt in lstarray
                          where authlt.AuthNum == authnum
                          select authlt.authLetter;

i tried opening a pdf by giving the authval to binary writer so that a new window in which pdf will appear. but its not working. it is asking me to give a byte array which i am unable to get from the string value.

is there a way to copy all the string char by char into byte array???
any other way to display pdf from the string?



any help is appreciated.

解决方案

Try:

byte[] array = Encoding.UTF8.GetBytes("Hello world!");
