Hi,

Use "Y" to get a string. A literal within single quotes is a character.

Singe quotes in that context imply char rather than string.  It means you are encoding a single character into data type char.  For a string, use double quotes.

Try

if (dt.Rows[0]["Eligible"].ToString() == "Y")

C# deferent than VB that has auto convertion feature.

Ie, In VB you can compare a text with a number.

But in C#, if you compare two object you must ensure that both object have same type.

Comparing chars

        if(Convert.ToChar(dt.Rows[0]["Eligible"])=='y')
        {

        }

Comparing strings

        if (dt.Rows[0]["Eligible"].ToString() == "y")
        {

        }
