 private string GetAccessor(DataAttribute attr, string rootTblName)
        {
            return string.Format("get { return {0}.{1}; }",

Use double braces {{ to escape curly braces in Format.

Suppose if the error message is coming from database, how can we escape with double braces. We can't update in the database because it is using in some other scenarios. – Ashok Yaganti Oct 07 '21 at 21:28

Escape them with {{ and }}.

Then it will work.

Eg:

string.Format("get {{ return {0}.{1}; }}", ....
