我们如何处理stackoverflow异常C＃

Question

I am writing C# on Umbraco CMS, then Microsoft Visual Studio detects that I should handle the stackoverflow error on

var umbracoHelper = new Umbraco.Web.UmbracoHelper(Umbraco.Web.UmbracoContext.Current);
Image = umbracoHelper.Media(imageId).GetCropUrl("umbracoFile", "image");

How I can handle this issue? You can see the full code on this link. https://drive.google.com/open?id=0B6cMfQEoDEfwdnczSDRJakJIMzA

Umbraco version 7.2.8

Tool: Microsoft Visual Studio 2013

I don't have the necessary reputation to be able to comment on your original question hence this "answer" - so I apologise in advance.

There's nothing in your code example that would throw StackOverflowException around the lines you've indicated, so you need to look deeper. You might possibly get a NullReferenceException on the GetCropUrl() extension method though as you haven't tested to make sure the meda item returns a valid object.

So everyone else doesn't have to download it - here's your code snippet (minus the usings/namespace):

public class Case
{
    public Case(IPublishedContent content) 
    {
        Id = content.Id;
        Description = content.GetPropertyValue<string>("description");
        Title = content.GetPropertyValue<string>("title");

        //image
        string image = content.GetPropertyValue<string>("image");            
        int imageId = 0;
        int.TryParse(image, out imageId);
        if (imageId != 0)
        {

                var umbracoHelper = new Umbraco.Web.UmbracoHelper(Umbraco.Web.UmbracoContext.Current);
                Image = umbracoHelper.Media(imageId).GetCropUrl("umbracoFile", "image");          
        }



        //Team
        string teamID = content.GetPropertyValue<string>("teamMember");
        Team = DAL.GetTeamProperties(teamID);
    }

    public Case() { }
    public int Id { get; set; } 
    public string Title { get; set; }            
    public string Description { get; set; }
    public string Image { get; set; }
    public List<Team> Team { get; set; }
}

It's more likely that your problem lies here rather than the code extracting the Image Url:

Team = DAL.GetTeamProperties(teamID);

However more information is needed - can you post the actual stack trace of the exception?
