I'm currently unable to get the value of an index belonging to the test variable. I try doing test[0] but get the error "Cannot apply indexing with [] to an expression of type 'object'. I am curious what other ways I can attempt so that these list elements can be accessed which belong to the Value of my dictionary.
Your value seems to be of type object, and as the error suggests you can't directly apply indexing to it. You have to cast it to a List<string> to use test[0].

I have 2 PowerPoints one original and one edited. I each PowerPoint I have a textbox that contains a number of words. The idea is to find any words added or deleted from the original PowerPoint in the edited and put them in a list. I then want to put a strike though these words that have been added or deleted but I can't access any of the properties I need as I have a string and not a TextFrame. Any ideas how I could strike through the words? E.g original "This Text" edited "This New Text" outcome "This New Text".
My code is as fallows

I am attempting to insert data from two List.
I am able to successfully insert from one List but adding the second list using a foreach loop does not work as expected.
How do I loop through each of these list so that I can insert their values?
Code:
private void InsertList()
{
var listA = new List<string>();
var listB = new List<string>();
//Populate both list by splitting items in listbox
foreach (ListItem item in ListBox1.Items)
{
var components = item.Value.Split('/');
listA.Add(components.First());
listB.Add(components.Last());
}
using (DataContext dataContext = new DataContext())
{
foreach (var itemA in listA)
{
foreach (var itemB in listB)
{
LIST_OBJECTS listObject = new LIST_OBJECTS
{
LIST_ITEM_A = itemA,
LIST_ITEM_B = itemB
};
dataContext.LIST_OBJECTS.Add(listObject);
}
}
dataContext.SaveChanges();
}
}
What about a for loop?
for (var i = 0; i < listA.Count; i++)
{
LIST_OBJECTS listObject = new LIST_OBJECTS
{
LIST_ITEM_A = listA[i],
LIST_ITEM_B = listB[i]
};
dataContext.LIST_OBJECTS.Add(listObject);
}
Since you know from the creation of the Lists that they'll have the same number of elements, this is fine.
You can do it with LINQ
LIST_OBJECTS listObject = listA.Join(listB,
a=>listA.Indexof(a),
b=>listB.Indexof(b),
(a,b)=> new LIST_OBJECTS()
{
LIST_ITEM_A =a,
LIST_ITEM_B =b
}).ToList();

string responser = contents.Substring(f + firstTag.Length, g - f - firstTag.Length);
foreach (List<string> subList in Threads)
{
}
}
}
}
I created this variable :
List<List<string>> Threads = new List<List<string>>();
The first thing I don't know yet how to do is how to create inside Threads number of Lists according to the FilteredLinks.Count inside the Links method.
Second thing is in the GetResponsers method I did:
foreach (List<string> subList in Threads)
{
}
But what I want is that first time it will add all the values from variable responser to the first List in Threads. Then when it's getting to the break; it stop then and then in the Links methods its calling GetResponsers(cont); again this time I want that all the values in responser to be added to the second List in Threads.
I know that each time it's getting to the break; it will get the next FilteredLink from FilteredLinks.
How do I create number of Lists in Threads according to the FilteredLinks.Count?
How do I make the code in GetResponsers to add the responser ?
You don't need to specify the count for the number of lists in Threads, since it is a list, you can simply keep adding lists to it. So the first part is correct where you are declaring it.
The second part --> Your calling method will change. Look below for the calling method.
The third part --> Change private void GetResponsers(string contents) to private void GetResponsers(List threadList, string contents). Look below for implementation change.
Also the loop will look like this then
//other code you have
List<List<string>> Threads = new List<List<string>>();
public void Links(string FileName)
{
// ...other code you have
for (int i = 0; i < FilteredLinks.Count; i++)
{
threads.Add(new List<string>);
contents.Encoding = System.Text.Encoding.GetEncoding(1255);
cont = contents.DownloadString(FilteredLinks[i]);
GetResponsers(threads[threads.Count - 1], cont);
}
}
private void GetResponsers(List<string> threadList, string contents)
{
int f = 0;
int startPos = 0;
while (true)
{
string firstTag = "<FONT CLASS='text16b'>";
string lastTag = "&n";
f = contents.IndexOf(firstTag, startPos);
if (f == -1)
{
break;
}
int g = contents.IndexOf(lastTag, f);
startPos = g + lastTag.Length;
string responser = contents.Substring(f + firstTag.Length, g - f - firstTag.Length);
threadList.Add(responser);
}
}

How do i make List of Lists ? And then add to each List values?
The following codesnippet demonstrates you, how to handle List<List<string>>.
List<List<string>> threads = new List<List<string>>();
List<string> list1 = new List<string>();
list1.Add("List1_1");
list1.Add("List1_2")
threads.Add(list1);
List<string> list2 = new List<string>();
list1.Add("List2_1");
list1.Add("List2_2")
list1.Add("List2_3")
threads.Add(list2);
How do i create number of Lists in Threads according to the
FilteredLinks.Count ?
for(int i = 0; i < FilteredLinks.Count; i++)
{
var newList = new List<string>();
newList.Add("item1"); //add whatever you wish, here.
newList.Add("item2");
Threads.Add(newList);
}
I'm afraid I can't help you with Question #2, since I don't understand what you try to achieve there exactly.
I'm rather new to Linq. I'm having trouble coding this.
I have a list with many different sublists.
oldList[0] some type
oldList[1] another different type
oldList[2] the type I want
oldList[3] more types
I want to select all the parameters from a specific type and write them to a temp list.
If that temp list is empty, I want to assign some values (values don't actually matter).
After changing the values, I want to write temp list back into oldList.
Please advise. This is a huge learning experience for me.
public void myFunction(list)
{
//list contains at least 5 sublists of various type
//check if the type I want is null
IEnumerable<TypeIWant> possiblyEmptyList = list.OfType<TypeIWant>(); //find the type I want from the list and save it
if (possiblyEmptyList == null) //this doesn't work and possiblyEmptyList.Count <= 1 doesn't work
{
//convert residence address to forwarding address
IEnumerable<ReplacementType> replacementList = list.OfType<ReplacementType>();
forwardingAddress = replacementList.Select(x => new TypeIWant /* this statement functions exactly the way I want it to */
{
Address1 = x.Address1,
Address2 = x.Address2,
AddressType = x.AddressType,
City = x.City,
CountryId = x.CountryId,
CountyRegion = x.CountyRegion,
Email = x.Email,
ConfirmEmail = x.ConfirmEmail,
Fax = x.Fax,
Telephone = x.Telephone,
State = x.State,
PostalCode = x.PostalCode
});
//write forwarding address back to list
//don't know how to do this
}
LINQ purpose is querying. It doesn't allow you to replace some items in collection with other items. Use simple loop instead:
IEnumerable<TypeIWant> possiblyEmptyList = list.OfType<TypeIWant>();
if (!possiblyEmptyList.Any())
{
for (int i = 0; i < list.Count; i++)
{
ReplacementType item = list[i] as ReplacementType;
if (item == null)
continue;
list[i] = ConvertToTypeIWant(item);
}
}
And conversion (which is better to do with something like automapper):
private TypeIWant ConvertToTypeIWant(ReplacementType x)
{
return new TypeIWant
{
Address1 = x.Address1,
Address2 = x.Address2,
AddressType = x.AddressType,
City = x.City,
CountryId = x.CountryId,
CountyRegion = x.CountyRegion,
Email = x.Email,
ConfirmEmail = x.ConfirmEmail,
Fax = x.Fax,
Telephone = x.Telephone,
State = x.State,
PostalCode = x.PostalCode
};
}
Not LINQ but an example.
