数组创建与分析:  
例子一:  
string strValue = "{\"ldh\":\"001\",\"gfc\":\"002\",\"yyj\":\"003\",\"andy\":[\"005\",\"123\",\"true\"]}";  
Json::Reader read;  
Json::Value value;  
value["ldh"] = "001";  
value["gfc"] = "002";  
value["andy"].append( "005" );  
value["andy"].append( "123" );  
value["andy"].append( "true" );  
//if( read.parse( strValue,value ) )  
{  
Json::Value val_array = value["andy"];  
int iSize = val_array.size();  
for ( int nIndex = 0;nIndex < iSize;++ nIndex )  
{  
cout<<val_array[nIndex]<<endl;  
}  
}  
  
  
例子二:  
Json::Reader read;  
Json::Value value;  
value["ldh"] = "001";  
value["gfc"] = "002";  
Value item;  
Value array;  
item["andy1"] = "005";  
array.append( item );  
item["andy1"] = "123";  
array.append( item );  
item["andy1"] = "true";  
array.append( item );  
value["andy"] = array;  
cout<<value.toStyledString()<<endl;  
Json::Value val_array = value["andy"];  
int iSize = val_array.size();  
for ( int nIndex = 0;nIndex < iSize;++ nIndex )  
{  
cout<<val_array[nIndex]<<endl;  
if ( !val_array[nIndex]["andy1"].isNull() )  
{  
cout<<val_array[nIndex]["andy1"]<<endl;  
}  
}  
  
  
例子三:  
std::string strValue = "{\"name\":\"json\",\"array\":[{\"cpp\":\"jsoncpp\"},{\"java\":\"jsoninjava\"},{\"PHP\":\"support\"}]}";    
Json::Value value;  
Reader read;  
if ( !read.parse( strValue,value ) )  
{  
return -1;  
}  
cout<<value.toStyledString()<<endl;  
Json::Value val_array = value["array"];  
int iSize = val_array.size();  
for ( int nIndex = 0;nIndex < iSize;++ nIndex )  
{  
cout<<val_array[nIndex]<<endl;  
if ( val_array[nIndex].isMember( "cpp" ) )  
{  
cout<<val_array[nIndex]["cpp"]<<endl;  
}  
}  
  
getchar();  
return 0;  
}
