C#初始化数组的方法小结

本文实例讲述了c#初始化数组的方法。分享给大家供大家参考，具体如下：

c#声明数组并初始化，有三种方式。

对于一维数组：

using system;
using system.data;
using system.configuration;
using system.web;
using system.web.security;
using system.web.ui;
using system.web.ui.webcontrols;
using system.web.ui.webcontrols.webparts;
using system.web.ui.htmlcontrols;
public partial class _default : system.web.ui.page
{
  protected void page_load(object sender, eventargs e)
  {
    string[] arraya = { "shirdrn", "hamtty", "saxery" };
    response.write("<b>第一种声明数组并初始化的方法：</b><br>");
    for (int i = 0; i < arraya.length;i++ )
    {
      string arr = arraya[i];
      response.write("arraya[" + i + "] = " + arr + "<br>");
    }
    string[] arrayb ;
    arrayb = new string[3]{ "shirdrn", "hamtty", "saxery" };
    response.write("<b>第二种声明数组并初始化的方法：</b><br>");
    for (int i = 0; i < arrayb.length; i++)
    {
      string arr = arrayb[i];
      response.write("arrayb[" + i + "] = " + arr + "<br>");
    }
    string[] arrayc = new string[3];
    arrayc[0] = "shirdrn";
    arrayc[1] = "hamtty";
    arrayc[2] = "saxery";
    response.write("<b>第三种声明数组并初始化的方法：</b><br>");
    for (int i = 0; i < arrayc.length; i++)
    {
      string arr = arrayc[i];
      response.write("arrayc["+i+"] = "+arr + "<br>");
    }
  }
}

对于多维数组(以二维数组为例)：

using system;
using system.data;
using system.configuration;
using system.web;
using system.web.security;
using system.web.ui;
using system.web.ui.webcontrols;
using system.web.ui.webcontrols.webparts;
using system.web.ui.htmlcontrols;
public partial class _default : system.web.ui.page
{
  protected void page_load(object sender, eventargs e)
  {
    string[,] multiarraya = { { "shirdrn", "hamtty", "tuuty" }, { "new york", "beijing", "shanghai" } };
    response.write("<b>第一种声明数组并初始化的方法：</b><br>");
    for (int i = 0; i < multiarraya.rank; i++)
    {
      for (int j = 0; j <= multiarraya.getupperbound(multiarraya.rank-1);j++ )
      {
        string arr = multiarraya[i,j];
        response.write("multiarraya[" + i + "]["+j+"] = " + arr + "<br>");
      }
    }
    string[,] multiarrayb = new string[2,3]{ { "shirdrn", "hamtty", "tuuty" }, { "new york", "beijing", "shanghai" } };
    response.write("<b>第二种声明数组并初始化的方法：</b><br>");
    for (int i = 0; i < multiarrayb.rank; i++)
    {
      for (int j = 0; j <= multiarrayb.getupperbound(multiarrayb.rank - 1); j++)
      {
        string arr = multiarraya[i, j];
        response.write("multiarrayb[" + i + "][" + j + "] = " + arr + "<br>");
      }
    }
    string[,] multiarrayc = new string[2, 3];
    multiarrayc[0,0] = "shirdrn";
    multiarrayc[0,1] = "hamtty";
    multiarrayc[0,2] = "tuuty";
    multiarrayc[1,0] = "new york";
    multiarrayc[1,1] = "beijing";
    multiarrayc[1,2] = "shanghai";
    response.write("<b>第二种声明数组并初始化的方法：</b><br>");
    for (int i = 0; i < multiarrayc.rank; i++)
    {
      for (int j = 0; j <= multiarrayc.getupperbound(multiarrayc.rank - 1); j++)
      {
        string arr = multiarraya[i, j];
        response.write("multiarrayc[" + i + "][" + j + "] = " + arr + "<br>");
      }
    }
  }
}
