以前看过很多用非托管代码实现的调用WEB服务，今天自己亲自用托管C++来做一下，毕竟以前没有专门学过C++，一直用C#了，这回返回来学习下C++.NET。

首先打开VS2008，然后新建一个项目，选择CLR，然后选择Windows窗体应用程序。
然后就OK了。接下来，拖几个控件上去，方便显示。。。简单的，两个button，一个textBox就行了。
然后双击第一个按钮，进入以下界面。。。能看到button_click按钮单机事件，在里面写代码。
然后先别动它，双击第二个按钮，在第二个按钮单击事件里写this->Close();关闭窗体：
接下来，就是要添加WEB服务了。。。对着项目点右键，添加web引用。。。
按照箭头顺序来，即可。
然后你会发现项目里多了一些文件。。。
接下来。。。什么也不用做，写代码吧：
在button1的click事件里写如下代码：
WeatherService::Service^ WS = gcnew WeatherService::Service ();
array<Object^>^ myarr = WS->getWeatherbyCityName ("北京",WeatherService::theDayFlagEnum ::Today);
for(int i =1; i <7 ; i ++)
{
textBox1->Text += myarr[i];
}
然后，F6，编译，CTRL+F5运行。。。100%成功。。。效果如下：
参考MSDN：
using namespace System;
void main1(); void main2();
void main()
{
main1();
Console::WriteLine();
main2();
}
void PrintValues( array<Object^>^myArr );
void PrintValues( array<int>^myArr );
void main1()
{
// Creates and initializes a new int array and a new Object array.
array<int>^myIntArray = {1,2,3,4,5};
array<Object^>^myObjArray = {26,27,28,29,30};
// Prints the initial values of both arrays.
Console::WriteLine( "Initially," );
Console::Write( "int array: " );
PrintValues( myIntArray );
Console::Write( "Object array:" );
PrintValues( myObjArray );
// Copies the first two elements from the int array to the Object array.
Array::Copy( myIntArray, myObjArray, 2 );
// Prints the values of the modified arrays.
Console::WriteLine( "\nAfter copying the first two elements of the int array to the Object array," );
Console::Write( "int array: " );
PrintValues( myIntArray );
Console::Write( "Object array:" );
PrintValues( myObjArray );
// Copies the last two elements from the Object array to the int array.
Array::Copy( myObjArray, myObjArray->GetUpperBound( 0 ) - 1, myIntArray, myIntArray->GetUpperBound( 0 ) - 1, 2 );
// Prints the values of the modified arrays.
Console::WriteLine( "\nAfter copying the last two elements of the Object array to the int array," );
Console::Write( "int array: " );
PrintValues( myIntArray );
Console::Write( "Object array:" );
PrintValues( myObjArray );
}
void PrintValues( array<Object^>^myArr )
{
for ( int i = 0; i < myArr->Length; i++ )
{
Console::Write( "\t{0}", myArr[ i ] );
}
Console::WriteLine();
}
void PrintValues( array<int>^myArr )
{
for ( int i = 0; i < myArr->Length; i++ )
{
Console::Write( "\t{0}", myArr[ i ] );
}
Console::WriteLine();
}
