从 json 字符串中删除 unicode BEL \u0007 特殊字符

Question

我有第三方API的JSON响应，并且我正在尝试使用C＃代码将其转换为XML文件。 文本视图中的响应字段：

“描述”：“ \ u0007 \ tpost-show seet＆amp;迎接photo \ r \ n \ u0007 \ tpremium tpremium seat s r \ r \ r \ r \ n \ u0007 \，

但在转换此i时我得到了

system.argumentException：''，十六进制值0x07，是无效的字符。

我尝试过

1. Regex：Regex.Replace（内容，“ [^\ x00- \ x7f]”，string.empty）和Regex（@“ [^\ u0000- \ u0077f]”，regexoptions.com.poiled）;
2. 编码：encoding.ascii.getString（encoding.ascii.getBytes（content））;
3. ASCII检查以跳过值＆gt; 255
4. 分解成阵列以替换为空字符串或用system.xml.xmlconvert.isxmlchar检查每个字符，但是U0007分解为5个不同的字符，

但到目前为止没有运气。
