Solution 3

you can use for loop :

C#

for (int i=0;i<ds.tables[0].rows.count;i++)>
{
string value=ds.Tables[0].Rows[i]["Col1"].Tostring();
string vlue2=ds.Tables[0].Rows[i]["Col2"].Tostring();

}

You are fetching a single column "userid" by your adapter:

SqlDataAdapter da = new SqlDataAdapter("select userid from user_detail", con);

If you want to use it somewhere then apply a foreach loop and fetch the "userid".

C#

foreach(DataRow row in ds.Tables[0].Rows) {
   int uid = Convert.ToInt(row["userid"]);
}

You can use a code like this:

C#

foreach(DataRow row in ds.Tables[0].Rows) {
   string col1 = row["Col1"].ToString();
}
