小编Rup*_*dav的帖子

我想解析aspx页面中的值,两者之前传递的是什么？之后呢？那么,什么是允许我解析出来的C#函数呢？

我想做的事情如下:

var pageType = parameter.trimBefore?();

var pageString = parameter.trimAfter?();

谢谢你的建议.

当我尝试创建方法的实例时,我收到EXC_BAD_ACCESS错误.

UIImageView *img = [[UIImageView alloc] initWithFrame:CGRectMake(40,38,240,203)];
DetailImageViewDataSource *detail=[[DetailImageViewDataSource alloc] init];//**error line**

@implementation DetailImageViewDataSource


@synthesize webdata,xmlParser,soapResults,newImage;
-(void) startParsing
{
    recordResults=FALSE;
    NSString *soapMessage=[NSString stringWithFormat:
                           @"<?xml version=\"1.0\" encoding=\"utf-8\"?>"

                           "</GetImage>\n"
                           "</soap:Body>\n"
                           "</soap:Envelope>\n"];

NSLog(soapMessage);
NSURL *url=[NSURL URLWithString:@"http://192.168.2.7/ThesisWebServicesNew1/Service.asmx"];
NSMutableURLRequest *theRequest=[NSMutableURLRequest requestWithURL:url];
NSString *msgLength=[NSString stringWithFormat:@"%d",[soapMessage length]];

if(theConnection)

    webdata=[[NSMutableData data] retain];

    NSLog(@"got connected");
}

else
{ …

ITool GetTool(Guid tool)
{
    if (tool == Hammer.Id)
        return new Hammer();
    else if (tool == Drill.Id)
        return new Drill();

    else
        throw new ....?
}

扔在这里最合适的异常类型是什么？NotSupportedException是我发现的最接近但我不认为这是正确的.

我使用"http://maps.googleapis.com/maps/api/geocode/xml?address="+address+"&sensor=true"来获取某个位置的纬度和经度.从这个我得到如下响应:

响应具有许多位置的lng和lat值.那么我要考虑哪一个？
