text:js Using a StringBuilder

As a newcomer to the .NET platform, I am eager to learn how to pass a JS function with curly brackets as a string inside StringBuilder.AppendFormat() in C#. Below is my desired approach:

StringBuilder sb = new StringBuilder();

sb.AppendFormat(@"<script>
       var vm = new Vue({
        el: 'main_div',
        data() { 
            return {
                proddetails: [],
            }
        },
        created: function () {
            this.proddetails = { jsonobjectplaceholder };
        },
    });
</script>");

Apologies for any ignorance on my part, and thank you in advance for the help!

Make sure to escape curly braces when using AppendFormat in C#. You can achieve this by doubling the curly braces like {{ and }}. Here is an example:

Reference: Escape curly brace '{' in String.Format

sb.AppendFormat(@"<script>
       var vm = new Vue({{
        el: 'main_div',
        data() {{ 
            return {{
                proddetails: [],
            }}
        }},
        created: function () {{
            this.proddetails = {{ jsonobjectplaceholder }};
        }},
    }});
</script>", "");

Alternatively, you can simply use Append instead of AppendFormat. Here's how:

StringBuilder sb = new StringBuilder();

sb.Append(@"<script>
       var vm = new Vue({
        el: 'main_div',
        data() { 
            return {
                proddetails: [],
            }
        },
        created: function () {
            this.proddetails = { jsonobjectplaceholder };
        },
    });
</script>");

Your code appears to contain 'AppendFormat', but perhaps you intended to use 'Append' instead?

When using 'StringBuilder.AppendFormat', you are able to format a string with an array of strings.

For example:

sb.AppendFormat("{0}, {1}, {2}", "var1", "var2", "var3");

The result will be: "var1, var2, var3"

If you want to include multiple lines in a string, you can use the '@' symbol as a verbatim identifier.

For more information, check out this link: Click Here

string exampleString = $@"This
is a
string";

To achieve the desired code structure, it should look like the following:

StringBuilder sb = new StringBuilder();
sb.Append(@"<script> var s = 'myStringValue'; </script>");
