我想将其转换为字节[]



如果我转换它使用



byte [] Barcode_ImageByte = Convert.FromBase64String（转换）;



然后它给出一个错误



输入不是有效的Base-64字符串，因为它包含一个非基数为64的字符，两个以上的填充字符或填充字符中的非法字符。

I want Convert it Into byte[]

if i convert it using

byte[] Barcode_ImageByte = Convert.FromBase64String(converted);

then it gives an error

The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters.

If anybody Knows then Help Me About that

推荐答案

它看起来你的字符串中有一个虚假的尾巴（：195）。

如果删除这样的尾部，则剩余部分被正确解码。

It looks there is a spurious tail (":195") in your string.
If you remove such tail then the remaining part is correctly decoded.
