Question

我收到，我很伤心地说，我不知道很多有关处理64base字符串错误。目前我已经将此错误跟踪到这行代码：

byte[] jobData = Convert.FromBase64String(base64JobData);

这是我的XML，它被传递到base64JobData，但我似乎无法找到任何应该抛出此错误的内容。

有没有一种简单的方法可以找出这个xml字符串中有问题的字符是什么？或者一种可以帮助我找到失败原因的工具。

Answer 1

我认为你的问题可能令人困惑，或者对函数的行为有误解。这个函数是转换FROM base64，所以如果你给它上面的XML提供，那将无法工作。该函数期望base64编码的字符串。

以下是MS的链接 - frombase64string

哪种状态，“将指定的字符串转换为等效的8位无符号整数数组，将二进制数据编码为基数为64的数字。”

参数字符串“s” - s由base-64数字，空格字符和尾随填充字符组成。从零开始的基数为64的数字是大写字母“A”到“Z”，小写字母“a”到“z”，数字“0”到“9”，符号“+”和“/” ”

带有XML的base64字符串中的字符无效
