如何在另一个char数组中复制char数组？ [英] How can I copy a char array in another char array?

问题描述

您好，



是否有方法或方法在char数组（大小为64）中复制char数组（例如大小为8）。



我尝试了什么：



我已经尝试过使用某些方法像Array.Copy和copyto（）但它没有用。

我的结果char数组总是/ 0/0/0/0 .....

 public int CAN_DefineTransmit（int canNo，int iD，int cycleMs，int offsetMs，int length，char [] frame）
 {
 int ret; 
 this.ReadBuffer（）; 
 this.CANDIAG_CommandBufferInit（）; 
 
 this.buff.Param [1] .IValue = canNo; 
 this.buff.Param [2] .IValue = iD; 
 this.buff.Param [3] .IValue = cycleMs; 
 this.buff.Param [4] .IValue = offsetMs; 
 this.buff.Param [5] .IValue = length; 
 if（（长度< 8&&长度> = 0）||长度> 8）
 {
 Array.Copy（frame，0，this.buff.Param [3] .FrameFD，0，长度）; 
} 
 else 
 {
 Array.Copy（frame，0，this.buff.Param [3] .FrameFD，0,8）; 
} 
 
 // this.buff.Param [6] .FrameFD = frame; 
 ret = this.CANDIAG_Client_SendCommand（501）; 
 this.WriteBuffer（）; 
返回this.CANDIAG_CommandBufferExit（）; 
} 
 

帧FD是在结构中声明的64个字符数组。

  char  [] input =   Hello！这是文本。 .ToCharArray（）; 
  char  [] output =  new   char  [ 64 ]; 
 Array.Copy（input，output，input.Length）; 
  for （ int  i =  0 ; i <  output.Length; i ++）
 {
  char  c =输出[i]; 
 Console.WriteLine（  {0}：{1：X02}， char  .IsControl（c）？'  *' ：c，（ int ）c）; 
} 

此示例应该可以正常工作... Array.copy（）将源数组的范围复制到您选择的指定数组。

我希望这会有所帮助：

  char  [] myarray =  new   char  [ 5 ]; 
 myarray2 =  new   char  [ 64 ]; 
复制（myarray，myarray2， 5 ）; 
 

Hello,

Is there a method or a way to copy a char array (for example of size 8) in a char array (of size 64).

What I have tried:

I already tried using some methods like Array.Copy and copyto() but it didn't worked.
My result char array was always /0 /0 /0 /0 .....

public int CAN_DefineTransmit(int canNo, int iD, int cycleMs, int offsetMs, int length, char[] frame)
{
    int ret;
    this.ReadBuffer();
    this.CANDIAG_CommandBufferInit();

    this.buff.Param[1].IValue = canNo;
    this.buff.Param[2].IValue = iD;
    this.buff.Param[3].IValue = cycleMs;
    this.buff.Param[4].IValue = offsetMs;
    this.buff.Param[5].IValue = length;
    if ((length < 8 && length >= 0) || length > 8)
    {
        Array.Copy(frame, 0, this.buff.Param[3].FrameFD, 0, length);
    }
    else
    {
        Array.Copy(frame, 0, this.buff.Param[3].FrameFD, 0, 8);
    }

    // this.buff.Param[6].FrameFD = frame;
    ret = this.CANDIAG_Client_SendCommand(501);
    this.WriteBuffer();
    return this.CANDIAG_CommandBufferExit();
}

Frame FD is a char array of 64 declared in a structure.

解决方案

Try this:

char[] input = "Hello! This is text.".ToCharArray();
char[] output = new char[64];
Array.Copy(input, output, input.Length);
for(int i = 0; i < output.Length; i++)
    {
    char c = output[i];
    Console.WriteLine("{0}:{1:X02}", char.IsControl(c) ? '*' : c, (int)c);
    }

This example should work fine... Array.copy() copies the range of the source array to the specified array of your choice.
I hope this helps:

char[] myarray = new char[5];
myarray2 = new char[64];
Copy(myarray, myarray2, 5);
