如何从frombase64string生成内存流？ [英] How to generate memorystream from frombase64string?

问题描述

我已经生成了一个随机字符串，使用DES算法加密它。



现在我正在尝试解密它，但在将加密字符串转换为内存流时遇到问题。



我的尝试：



我的代码如下：

I have generated a random string, Encrypted it using DES algorithm.

now I am trying to decrypt it, but facing problem while converting encrypted string into memory stream.

What I have tried:

my code is as follows:

public static MemoryStream Demo(string str)
       {
           MemoryStream memoryStream = new MemoryStream(Convert.FromBase64String(str));
           return memoryStream;
       }

加密字符串如下：

Encrypted string is as below:

rb3Cmy54Q8sANMHkelt9QzqOnM3enifu6v7AG5567oiqDk5ijwSwcSzfxUgHm4xD

在调试模式下将加密字符串转换为内存流时出错的错误如下所示< br $> b $ b

Error which I am getting while converting encrypted string into memorystream in debugging mode is as below

ReadTimeout = 'memoryStream.ReadTimeout' threw an exception of type 'System.InvalidOperationException'
WriteTimeout = 'memoryStream.WriteTimeout' threw an exception of type 'System.InvalidOperationException'

有什么问题吗用这个方法，或者我做错了吗？

is there any problem with the method, or I'm doing it wrong way?

推荐答案

检查你的数据：什么时候我复制并粘贴您的代码和数据：

Check your data: When I copy and paste your code and data:

private void butTestIt_Click(object sender, EventArgs e)
    {
    string str = "rb3Cmy54Q8sANMHkelt9QzqOnM3enifu6v7AG5567oiqDk5ijwSwcSzfxUgHm4xD";
    MemoryStream ms = Demo(str);
    }

public static MemoryStream Demo(string str)
    {
    MemoryStream memoryStream = new MemoryStream(Convert.FromBase64String(str));
    return memoryStream;
    }

我没有得到任何错误：缓冲区很好，长度为48个字节。

I get no error at all: the buffer is fine, and 48 bytes long.
