Question

我正试图将C代码转换为C＃，却偶然发现了一行代码，但我在转换时遇到了问题。

sprintf((char*)&u8FirmareBuffer[0x1C0] + strlen((char*)&u8FirmareBuffer[0x1C0]), ".B%s", argv[3]);

特别是这一行。 u8FirmwareBuffer是C中的一个无符号char数组，我猜是C＃中的一个字节数组。 argv [3]是一个字符串。如何将这行代码转换为C＃。

谢谢您的帮助。

编辑：这已被标记为重复项，但我认为它们之间存在差异，因为我使用的指针不适用于标记的帖子上提供的解决方案。

您可以执行以下操作：

string myString = "This is my string";
byte[] buffer = new byte[1024];
int offset = 0;

    // if you pass a byte buffer to the constructor of a memorystream, it will use that, don't forget that it cannot grow the buffer.
using (var memStream = new MemoryStream(buffer))
{
    // you can even seek to a specific position
    memStream.Seek(offset, SeekOrigin.Begin);

    // check your encoding..
    var data = Encoding.UTF8.GetBytes(myString);

    // write it on the current offset in the memory stream
    memStream.Write(data, 0, data.Length);
}

StreamWriter

也可能

string myString = "This is my string";
byte[] buffer = new byte[1024];
int offset = 0;

// if you pass a byte buffer to the constructor.....(see above)
using (var memStream = new MemoryStream(buffer))
using (var streamWriter = new StreamWriter(memStream))
{
    // you can even seek to a specific position
    memStream.Seek(offset, SeekOrigin.Begin);

    streamWriter.Write(myString);
    streamWriter.Flush();

    // don't forget to flush before you seek again
}

在C＃中将字符串打印到字节指针
