The conditional record set is met in the Linq query.

Query a dataset that meets the conditions in a able data set through linq

1. First define the variables of the query field, such as depth

String strDepth = query depth value;

Var dataRows = from datarow in able (dataTable dataset to be queried). AsEnumerable ()
Where
String. Compare (datarow. Field <string> ("query Field, such as depth Field"), strDepth) >=100 &&
String. Compare (datarow. Field <string> ("query Field, such as depth Field"), strDepth) <= 200
Select new
{
DT depth field name = datarow ["queried field, such as depth field"]. ToString (),
};

2. After directly calling the above linq statement, the above-mentioned linq means that the range of the Depth value of the query field is 100-200. You can re-query the field according to your project requirements.
