Cannot convert type 'char' to 'string

I am getting this error in one project and the code works perfectly fine on another project. I have tried multiple to duplicate the code as it is. Is there a way to find where the error originated from??

@if (ViewBag.RolesForThisUser != null)
{
<div style="background-color:lawngreen;">
<table class="table">
<tr>
<th>
@Html.DisplayName("Roles For This User")
</th>
</tr>
<tr>
<td>
@foreach (string s in ViewBag.RolesForThisUser) //this line

<li>@s</li>

</td>
</tr>
</table>

I suspected ViewBag.RolesForThisUser itself already contains a string, neither an array nor collection of strings (e.g. string or List<string>), hence using foreach loop is pointless (and string itself contains char array which explains why type conversion failed). You can simply display it without foreach:

ViewBag.RolesForThisUser

string

string

List<string>

foreach

string

char

foreach

@if (!string.IsNullOrEmpty(ViewBag.RolesForThisUser))

<div style="background-color:lawngreen;">
<table class="table">
<tr>
<th>
@Html.DisplayName("Roles For This User")
</th>
</tr>
<tr>
<td>
@ViewBag.RolesForThisUser
</td>
</tr>
</table>
</div>



Or assign a string collection to ViewBag.RolesForThisUser from GET method so that you can use foreach loop, like example below:

ViewBag.RolesForThisUser

GET

foreach

Controller

public ActionResult ActionName()

var list = new List<string>();

list.Add("Administrator");
// add other values here

ViewBag.RolesForThisUser = list;

return View();



View

@if (ViewBag.RolesForThisUser != null)

<div style="background-color:lawngreen;">
<table class="table">
<tr>
<th>
@Html.DisplayName("Roles For This User")
</th>
</tr>
<tr>
<td>
@foreach (string s in ViewBag.RolesForThisUser)

<p>@s</p>

</td>
</tr>
</table>
</div>
