9 quintillion characters on a 64 bit system on CPython 3.10. That's only if your string is made up of only ASCII characters. The max length can be smaller depending on what characters the string contains due to the way CPython implements strings: 9,223,372,036,854,775,758 characters if...

若要增加配额,请使用相应绑定元素上的 MaxReceivedMessageSize 属性。 或者 错误:反序列化操作“GetAllUserData”的响应消息的正文时出现错误。读取 XML 数据时,超出最大字符串内容长度配额 (8192)。通过更改在创建 XML 读取器时所使用的 XmlDictionaryReaderQuotas 对象的 MaxStringContentLength 属性,可增加此配额。

下面是函数max_len的实现,使用了C语言标准库中的strlen函数来计算字符串的长度: #include <string.h> int max_len(char *s[], int n) { int max_length = 0; // 用于保存最大长度 for (int i = 0; i < n; i++) { int length = strlen(s[i]); // 计算当前字符串的长度 ...
int iMCC = enc.GetMaxCharCount( bytes.Length ); Console.Write( " {0,-3} :", iMCC ); // Decode the bytes and display the characters. char[] chars = new char[iCC]; enc.GetChars( bytes, 0, bytes.Length, chars, 0 ); Console.WriteLine( chars ); } } 注解 若要计算存储生成...
