Syntax error, '>' expected in Sitecore CMS

-
When I was a developer in a large corporation before, I was assigned to a Sitecore CMS project. While working on the CMS's services in getting the contents, I encountered an error as mentioned in a title post.

After doing some research, I found out that the CMS's parser does not recognize special characters of the data returned from it's search query.

So the workaround that I found from an article was to surround the data returned with hash tags.
In the sample codes below, I just added a snippet to insert hashtags to data returned from the parser.

Sample Data Returned: Tel-Aviv
Formatted data: #Tel-Aviv#

public static IEnumerable<IUniversity> GetSchoolsByState(Guid stateProvinceId, Language languageVersion)
{
    if (stateProvinceId.Equals(Guid.Empty))
        return null;
 
    var stateProvinceReferenceItem = Context.Database.GetItem(ID.Parse(stateProvinceId));
    if (stateProvinceReferenceItem == null)
        return null;
        
    return GetSchoolsByStateProvince(stateProvinceReferenceItem.Paths.Path, languageVersion);
}

    {
        path = path.Insert(path.LastIndexOf("/", StringComparison.Ordinal) + 1, "#");
        path = path.Insert(path.Length, "#");
        return GetSchoolsByStateProvince(path, languageVersion);
    }         
    
    return GetSchoolsByStateProvince(stateProvinceReferenceItem.Paths.Path, languageVersion);

For the connectionstring name in App.config file, I

How To Insert Or Add Emojis In Microsoft Teams Status Message

Good day Gents! I was trying to update my Microsoft Teams status and was wondering if I can add or insert emoji. For editing or adding new teams status, only text fields are available and there's no emoji icon similar to writing a teams message. After googling for a few minutes, I found this link Emoji's in status which is a feature request in Microsoft Teams User's Voice Forum. So far this upgrade request only has thirty votes which is relatively small and may be considered a low priority for the product team to implement. Given the limitations at hand, I tried several approach including copying an emoji in a chat message which didn't work and later found a solution using Microsoft Outlook 365. First is to create a new email message in Microsoft Outlook and press (Window Key + .). The emoji dropdown control will appear. Next is to select the emoji that you wanted to add to Teams. Copy the emoji from the newly created email message template and paste that to Micr

Pass GUID As Parameter To Action Using ASP.NET MVC ContribGrid

-
Hi, In a scenario where in you want to pass a GUID object to an Action Parameter, the parameter might contain a null value. Since Guid is not nullable, you can't simply just pass it to an action parameter because Action parameters require nullable and reference types. You might encounter an error like this: An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter Assuming you have an aspx view below: <div> <% Html.Grid(Model).Columns (c => { c.For(m => m.Price); c.For(m => m.ProductName); c.For(m => m.ProductID); c.For( "View Person" ).Named( "" ).Action(m => { %> <td> <%= Html.ActionLink( "View Person" , "ProductDetail" , "Home" , new { @id = m.ProductID.ToString() }) %> </td> <% }); %> <% }).Render(); %> </div> and an action
