c# - 对内存中的表运行 SQL 查询

Question

我有 2 个使用 SQL 查询加入的表

DataTable Table = Select FacilityIssueDetails.FacilityNo,LCPaymentDetails.BillNo, FacilityIssueDetails.FStatus,LCPaymentDetails.BankName , LCPaymentDetails.Supplier, FacilityIssueDetails.BaseAmount,FacilityIssueDetails.Currency, FacilityIssueDetails.FacilityAmountINR, LCPaymentDetails.PAmountINR , FacilityIssueDetails.LCAmountPaid, FacilityIssueDetails.LCAmountRemaining,FacilityIssueDetails.IssueDate, FacilityIssueDetails.ExpiryDate, LCPaymentDetails.LCNo 
                  from FacilityIssueDetails,LCPaymentDetails 
                  where FacilityIssueDetails.FacilityNo = LCPaymentDetails.LCNo

现在我想对存储在内存中的表运行另一个 SQL 查询。

怎么做？这是一个选择查询。

请帮助，提前谢谢。

使用DataTable.Select方法。请注意，与SELECT数据库相比，它的性能很慢。
