c#数组赋初值_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)
{
第⼀种声明数组并初始化的⽅法：
string[] arrayA = { "Shirdrn", "Hamtty", "Saxery" };        Response.Write("第⼀种声明数组并初始化的⽅法：
");
for (int i = 0; i < arrayA.Length;i++ )
{
string arr = arrayA[i];
Response.Write("arrayA[" + i + "] = " + arr + "
");
}
string[] arrayB ;
第⼆种声明数组并初始化的⽅法：arrayB = new string[3]{ "shirdrn", "Hamtty", "Saxery" };        Response.Write("第⼆种声明数组并初始化的⽅法：");
for (int i = 0; i < arrayB.Length; i++)
{
string arr = arrayB[i];
Response.Write("arrayB[" + i + "] = " + arr + "
");
}
string[] arrayC = new string[3];
arrayC[0] = "Shirdrn";
arrayC[1] = "Hamtty";
arrayC[2] = "Saxery";        Response.Write("第三种声明数组并初始化的⽅法：
第三种声明数组并初始化的⽅法：
");
for (int i = 0; i < arrayC.Length; i++)
{
string arr = arrayC[i];
Response.Write("arrayC["+i+"] = "+arr + "
");
}
}
}
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)
{
第⼀种声string[,] multiArrayA = { { "Shirdrn", "Hamtty", "Tuuty" }, { "New York", "Beijing", "Shanghai" } };        Response.Write("第⼀种声明数组并初始化的⽅法：
");
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 + "
");
}
}
string[,] multiArrayB = new string[2,3]{ { "Shirdrn", "Hamtty", "Tuuty" }, { "New York", "Beijing", "Shanghai" } };
第⼆种声明数组并初始化的⽅法：
Response.Write("第⼆种声明数组并初始化的⽅法：
");
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 + "
");
}
}
string[,] multiArrayC = new string[2, 3];
一维数组的定义和初始化multiArrayC[0,0] = "Shirdrn";
multiArrayC[0,1] = "Hamtty";
multiArrayC[0,2] = "Tuuty";
multiArrayC[1,0] = "New York";
multiArrayC[1,1] = "Beijing";
第⼆种声明数组并初始化的⽅法：
multiArrayC[1,2] = "Shanghai";        Response.Write("第⼆种声明数组并初始化的⽅法：
");
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 + "
");
}
}
}
}
