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>");      }    }  }}
