C#初始化數組的三種方式

C#聲明數組並初始化，有三種方式。

對於一維數組：

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>第一種聲明數組並初始化的方法：</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>第二種聲明數組並初始化的方法：</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>第三種聲明數組並初始化的方法：</b><br>");
for (int i = 0; i < arrayC.Length; i++)
{
string arr = arrayC[i];
Response.Write("arrayC["+i+"] = "+arr + "<br>");
}
}
}

對於多維陣列(以二維數組為例)：

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>第一種聲明數組並初始化的方法：</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>第二種聲明數組並初始化的方法：</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>第二種聲明數組並初始化的方法：</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>");
}
}

}
}
