I need solution for read connection string from text file

[nandha2808]

this code for aspx.cs:

 string inputString;
        resultLabel.Text = "";
        using (StreamReader streamReader = File.OpenText(@"E:\projects\readtxt\nan.txt"))
        {
            inputString = streamReader.ReadLine();
            while (inputString != null)
            {
                resultLabel.Text += inputString + "<br />";
                inputString = streamReader.ReadLine();
            }
        }

text file contains:

string con = new SqlConnection(C onfigurationMan ager.Connection Strings["nandhaconnecti onstring"].ConnectionStri ng);

i get error The ConnectionStrin g property has not been initialized.

Please use code tags when posting code or formatted data.

Reading data from a text file does not run code. You need to put the code in your source files and use the text file to supply only the string.

You already know how, you just need to move the code around. It's all there.

You know how to open and read from a file. You just need to move the code out of your text file and into the rest of the source code.

In pseudo code, you need to do something like this:

connectionStringFromFile = read line from text file
connection.connectionString = connectionStringFromFile

Where the file ONLY contains the connection string, not code.
