断言字符串数组不相等，但看起来相等

Question

我有两个字符串数组，似乎是相同的，当我检查他们。我是否使用了错误的Assert方法?

//Arrange
string[] expected = new[] { "Widget A", "Widget B" };
string[] actual;
//Act
actual = api.GetIncidents(credentials);
//Assert
Assert.AreEqual(expected, actual);
Assert.AreEqual failed. Expected:<System.String[]>. Actual:<System.String[]>.

Answer 1

您需要CollectionAssert。AreEqual方法，通常在断言集合时使用CollectionAssert类:

CollectionAssert.AreEqual(expected, actual);
