First, DataRow[] dr = dt.Select(" t1= 'a' "); The result is 1 array, and you just loop through the array.
Note that the value can also be obtained by specifying which line: if you want to obtain the filtered value for the first line, you can do so in the following sentence
string x=dr[0]["t2"].Tostring(); // Gets the value of the filtered t2 field in line 1.
string x="";
if (dr.Length > 0)
{
foreach (DataRow drN in dr)
{
x+=drN["t2"]; // After the loop obtains the filter conditions t2 The value of the column
}
}

string x=dr[0]["t2"].Tostring(); // Gets the value of the filtered t2 field in line 1.
