若文本框含<br>标签则条件需为假的代码实现问询

Let's break down your current code and how well it meets your stated requirement:

Current Code Limitation #

Your implementation has two checks:

1. Ensures notificationTextEnrolmentFeeSection is not null or empty
2. Ensures the string is exactly equal to <br> (the HTML-encoded version of <br>)

This only handles the narrow case where the text box contains nothing but the <br> tag. However, your requirement specifies the condition should be false if the text box contains the <br> tag at all—even if it's part of a longer string. For example, your current code would still render the table for strings like "Payment details <br> See below", which violates the requirement.

Correct Implementation #

To fix this, we need to check if the string does not contain the <br> tag (in its encoded form, as your original code uses):

@if (!string.IsNullOrEmpty(notificationTextEnrolmentFeeSection) && !notificationTextEnrolmentFeeSection.Contains("<br>"))
{
    <table class="reports-table table-striped table-bordered table-responsive page-break-after-avoid">
        <tr class="rowPrint">
            <th>
                <div class="font-bold letter-spacing">Fee Section</div>
            </th>
        </tr>
        <tbody>
            <tr class="rowPrint">
                <td>
                    <div>
                        @Html.Raw(notificationTextEnrolmentFeeSection) <!-- Optional: Use to render HTML content instead of encoded text -->
                    </div>
                </td>
            </tr>
        </tbody>
    </table>
}

Key Adjustments: #

• Replaced the exact equality check (!= "<br>") with a substring check (!Contains("<br>")) to catch any occurrence of the <br> tag
• Added a note about @Html.Raw: use this if you want to render the actual HTML content instead of displaying encoded text like <br>
• If your notificationTextEnrolmentFeeSection stores the raw <br> tag (not encoded), replace "<br>" with "
" in the Contains check

Edge Cases Handled: #

• Skips rendering if the string is null or empty
• Skips rendering if the string includes the <br> tag in any form
• Renders the table only when the string has valid content without any <br> tags
