Assume the above contents resides in a file. I want to write a snippet that removes any line which has empty string "" and put escape character before the middle quotations. The final output would be:
buildLetter.Append("</head>").AppendLine();
buildLetter.Append("<style type="text/css">").AppendLine();
The outer " .... " is not considered special chars. The special chars may be single quotation or double quotation. I could run it via find and replace feature of Visual Studio. However, in my case i want it to be written in c# or VB.NET

View 4 RepliesI have a dropdown list which has items bound to it using sql datasource.
In the database i have the numeric values corresponding to each item.
Now there are many such dropdown list's and on selection of each item i want to form a 14 digit numeric code,which i need to use further for some more functionality.
How can i convert a selected item from a dropdownlist to a numeric digit??or how can i bind the items in the dropdownlist to a database having numeric value for each item?
E.g if i select 'WT' from dropdown list the corresponding value for it in the database table is 39 so on form submit i want '39' to be formed in codebehind. likewise on selection of all items from different dropdown list the digit formed using codebehind should be '15487523568955'
