如何使Razor不显示特殊字符为html

Question

The page I'm working on displays content from a database in readonly input box. My problem is that it's displaying any special characters as the html code (ie: & displays as &). How do you get the code to display properly?

I'm using QuerySingle to connect to the database, don't know if that makes a difference. I'm new to using Razor. Any help is much appreciated.

Code in question:

var queryloan = "SELECT * FROM loans WHERE LoanId = @0";
var queryloandata = db.QuerySingle(queryloan, queryformstatus_submitted.doc_loanid);
<form class="jotform-form" action="submit-form.cshtml?isadmin=@(isadmin)&loanid=@(loanid)" method="post" name="form_30905105572145" id="30905105572145" accept-charset="utf-8">
<input type="hidden" name="formID" value="30905105572145" />
<input type="hidden" name="doc_id" value="@doc_id" />
<div class="form-all">
    <ul class="form-section">
        <li id="cid_3" class="form-input-wide">
            <div class="form-header-group">
                <h2 id="header_3" class="form-header">
                    Borrower Sources & Uses Summary
                </h2>
                    @if (queryformstatus_submitted.doc_approval == "Pending Approval" || queryformstatus_submitted.doc_approval == "Approved")
                    {
                        <text><br />
                        <br />
                        <div class="error">
                            This form has already been submitted and cannot be edited. It is for reference only.</div></text>
                    }
                    @if(userid != queryformstatus_submitted.doc_userid){
                    <text><br/><br/><div class="error">You may not edit this form. It is for reference only.</div></text>
              }

            </div>
        </li>
        <li class="form-line" id="id_4">
            <label class="form-label-left" id="label_4" for="input_4">
                1. Property Name: 
            </label>
            <div id="cid_4" class="form-input">

            <input type="text" class=" form-textbox" id="input_4" name="q4_1Property" size="40" value="@Helpers.checkEmptyPreFill(queryinputvalue,"q4_1Property",queryloandata.LoanName)"/>
            </div>
        </li>

I'm not sure but I believe it may be something in this helper function that's causing the html code:

@helper checkEmptyPreFill(IEnumerable<dynamic> queryinputvalue, string field_id, string defaultval, int cloned = 0) {  

var reqValue = queryinputvalue.FirstOrDefault(r => r.field_name.Equals(field_id));
var return_value = "";
if(reqValue != null){
    return_value = reqValue.field_data;
} else {
    return_value = defaultval;
}

if(cloned == 1){
    return_value = "";
}

@return_value

}

The razor helper returns a HelperResult object so you'll have to convert it to a string before you can call HtmlDecode on it. Replace:

@Helpers.checkEmptyPreFill(queryinputvalue,"q4_1Property",queryloandata.LoanName)

with the following:

@HttpUtility.HtmlDecode(Helpers.checkEmptyPreFill(queryinputvalue,"q4_1Property",queryloandata.LoanName).ToString())

I would also suggest that you move some of the logic and data access code out of your view and into a controller but this should give you the result that you'e after.
