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:

?

6
7
8
9
10
11

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):

    for (int i = 0; i < multiArrayA.Rank; i++)
    {
      for (int j = 0; j <= multiArrayA.GetUpperBound(multiArrayA.Rank-1);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>");
      }
    }
  }
}
