c# - 这可以完全通过 linq 完成吗？

Question

我有一个过程，在这个过程中我识别列表中的行 (unmatchedClient)，然后调用一个单独的方法来删除它们 (pingtree.RemoveNodes)。这似乎有点啰嗦，我可以通过将属性“DeleteFlag”的值设置为 true 来实现同样的目的。但是如何使用 linq 设置值？

var unmatchedClient = pingtree.Nodes.Where(x =>
    _application.LoanAmount < x.Lender.MinLoanAmount ||
    _application.LoanAmount > x.Lender.MaxLoanAmount ||
    _application.LoanTerm < x.Lender.MinLoanTerm ||
    _application.LoanTerm > x.Lender.MaxLoanTerm)
.Select(x => x.TreeNode)
.ToList();

pingtree.RemoveNodes(unmatchedClient);

提前致谢。

像这样？

pingtree.Nodes.Where(x =>
        _application.LoanAmount < x.Lender.MinLoanAmount ||
        _application.LoanAmount > x.Lender.MaxLoanAmount ||
        _application.LoanTerm < x.Lender.MinLoanTerm ||
        _application.LoanTerm > x.Lender.MaxLoanTerm)
        .Select(x => x.TreeNode)
        .ToList()
        .ForEach(n=> n.DeleteFlag = true);
