实体框架不比较字节数组

Question

我使用包含SHA512哈希的EF插入数据.然后我查找相同的数据,但没有返回结果:

var searchHash = requestToFind.GetSelfSha512Hash();
var foundRequest = _complianceContext.ScoreResults
    .Where(sr => sr.SearchHash == searchHash);

sr.SearchHash和searchHash都是byte [].

如果我取出Where子句,我会得到1个结果.任何想法为什么会这样？

Answer 1

等于运算符不像您期望的字节数组那样工作.尝试SequenceEqual.

var foundRequest = _complianceContext.ScoreResults
  .Where(sr => sr.SequenceEqual(searchHash));
