Hello,
i have a code in vb.net :
VB
Dim oDs As DataSet = GridView1.DataSource

and when i run this code,it shows no error.


when i convert to c-sharp :
DataSet oDs = GridView1.DataSource;<br />


it shows error:
Cannot implicitly convert type 'object' to 'System.Data.DataSet'. An explicit conversion exists (are you missing a cast?)

can anyone help me on this,i had been scratching my head for 2 days for this..i dont understand what is the cast means,what should we do with the code.

Had you been using Option Strict On and Option Explicit On as you ALWAYS should be you would have caught the same error.

Dim oDs As DataSet = DirectCast(GridView1.DataSource, DataSet)

Hi,

This is working with VB because in VB implicit conversion exists.
But in case of C#, you need to provide type cast information.
In C#, There is no implicit conversion.

Try this code
DataSet oDs = (DataSet)GridView1.DataSource;


It might help you.

thanks dude..that works :-)
Try this:

Dataset ds=new Dataset();

//Write your query..

gridview1.dataSource=ds;
   
Try:

DataSet oDs = (DataSet)GridView1.DataSource;

Try something like:

DataSet ds = (DataSet)GVemp.DataSource;
DataTable dt = ds.Tables[0];
