[英]How can I convert this method from C++ to C#?
Could someone explain how I'd write this to C#?有人可以解释我如何将其写入 C# 吗?
//byte[] buffer is priavte in the class
//it's for writing Packets (gameserver)
void writeString(int location, std::string value, int length) {
if (value.length() < length) {
memcpy(&buffer[location], value.c_str(), value.length());
memset(&buffer[location+value.length()], 0, length-value.length());
}
else memcpy(&buffer[location], value.c_str(), length);
}
The exact answer to your question is this.你的问题的确切答案是这样的。 This is a private method within a C# class (I also added the buffer byte array for clarity):
这是 C# class 中的私有方法(为清楚起见,我还添加了缓冲区字节数组):
byte[] buffer;
private void writeString(int location, string value, int length)
{
System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding();
if (value.Length < length)
{
Array.Copy(encoding.GetBytes(value), 0, buffer, location, value.Length);
Array.Clear(buffer, location, length - value.Length);
}
else Array.Copy(encoding.GetBytes(value), 0, buffer, location, length);
}
C++ to C# migration pointers: C++ 到 C# 迁移指针:
ASCIIEncoding.GetBytes
comes to mind. ASCIIEncoding.GetBytes
在脑海。 It takes your string as a parameter and returns a byte[]
buffer containing your string.它将您的字符串作为参数并返回包含您的字符串的
byte[]
缓冲区。
Are you trying to write binary data to a stream, file or similar?您是否尝试将二进制数据写入 stream、文件或类似文件? If so, you're probably better off using a BinaryWriter , as it natively supports serializing strings (and other types, too, for that matter).
如果是这样,您可能最好使用BinaryWriter ,因为它本身支持序列化字符串(以及其他类型,就此而言)。
Use something like this to convert the string to a byte array, then use a for loop to put those bytes into the byte array that is your message buffer and to zero-fill if necessary使用类似这样的东西将字符串转换为字节数组,然后使用 for 循环将这些字节放入作为消息缓冲区的字节数组中,并在必要时进行零填充
// C# to convert a string to a byte array.
public static byte[] StrToByteArray(string str)
{
System.Text.UTF8Encoding encoding=new System.Text.UTF8Encoding();
return encoding.GetBytes(str);
}
