have the below code pulling the data out of the spread sheet and getting it into an array,
but now need to get it into a single varable.
have tried
String abc;
            abc = excelCell[1,1];
but throws up a Cannot implicitly convert type 'object' to 'string'. An explicit conversion exists (are you missing a cast?)


Excel.Worksheet excelWorksheet = (Excel.Worksheet)excelSheets.get_Item(currentSheet);

            Excel.Range excelCell =  (Excel.Range)excelWorksheet.get_Range("A1", "E100");
            excelCell[1,2]= "dfddf";
   
            //       MessageBox.Show(excelCell[1][1].ToString());
            String abc;
            abc = excelCell[1,1];

You have the solution in your MessageBox. The MessageBox needs a String, and you are calling ToString to get it.

Since you want to assign to a String variable, do the same thing:

abc = excelCell[1,1].ToString();

i did try this but it returned a "System.__ComObject" were

excelCell[1,2]= "dfddf";
            String abc;
            String xyz;
            xyz = " data str";   this works fine

            abc = excelCell[1, 1].ToString();  this string returns a com_object not a string object to work with

string

Sorry, I forgot one bit of code.

abc = excelCell[1,1].ToString(); calls ToString on the Cell, not on its value, and this returns the type by default.

This is the right one:

abc = excelCell[1,1].Value.ToString();
