我试图揭露一个可编辑的Azure表存储表。 (如果很重要:要通过ODATA客户端LIB CTP赢得电话7。)在服务器端,我有一个DataServiceContext:TableServiceContext,iDataserviceupdateProvider

我可以添加和删除对象,但是当我尝试更新资源时,Savechanges()似乎没有“拾取”拨打setProperty中分配的值。

//Works fine
public object GetResource(IQueryable query, string fullTypeName)
    {
        var resource = query.Cast<MyDataModel>().SingleOrDefault();
        if (fullTypeName != null && resource.GetType().FullName != fullTypeName)
        {
            throw new ApplicationException("Unexpected type for this resource");
        }
        return resource;
    }

//Seems to work fine: gets called for each property.
public void SetValue(object targetResource, string propertyName, object propertyValue)
    {
        var propInfo = targetResource.GetType().GetProperty(propertyName);
        propInfo.SetValue(targetResource, propertyValue, null);
    }

//This gets called, but resource is not updated 
void IUpdatable.SaveChanges()
    {
        //Forwarding from IUpdatable.SaveChanges() to DataServiceContext.SaveChanges()
        base.SaveChanges();
    }

更新:答案是在setValue()中调用updateObject():

public void SetValue(object targetResource, string propertyName, object propertyValue)
    {
        var propInfo = targetResource.GetType().GetProperty(propertyName);
        propInfo.SetValue(targetResource, propertyValue, null);
        UpdateObject(targetResource);
    }
有帮助吗?

解决方案

更新:答案是在setValue()中调用updateObject():

public void setValue(object targetResource,字符串属性名称,对象属性value){var propinfo = targetResource.getType()。getProperty(propertyName); propinfo.setValue(targetResource,propertyValue,null); updateObject(targetResource); }
