我想在我的网页，以显示该客户的形象。我该怎么办呢？我应该解密了吗？或者是任何其他方式？任何帮助将AP preciated。问候，

解决方案

作为解码@Christophe格尔斯建议后
用

 字符串连接codedString =图像数据连接$ C $光盘作为基地64字符数组
字节[]数据= Convert.FromBase64String（EN codedString）;Response.BinaryWrite（数据）;

I want to display this customer image in my web page. How can I do it? Should I decrypt it? or it is in any other format? Any help will be appreciated. Regards,

解决方案

After decoding as @Christophe Geers suggested use

string encodedString = "your image data encoded as base 64 char array";
byte[] data = Convert.FromBase64String(encodedString);

Response.BinaryWrite(data);
