我试图将两个数组相互比较.我试过这段代码并得到以下错误.
static bool ArraysEqual(Array a1, Array a2)
{
if (a1 == a2)
return true;
if (a1 == null || a2 == null)
return false;
if (a1.Length != a2.Length)
return false;
IList list1 = a1, list2 = a2; //error CS0305: Using the generic type 'System.Collections.Generic.IList<T>' requires '1' type arguments
for (int i = 0; i < a1.Length; i++)
{
if (!Object.Equals(list1[i], list2[i])) //error CS0021: Cannot apply indexing with [] to an expression of type 'IList'(x2)
return false;
}
return true;

这失败了:
// Expected result.
List<string> expected = new List<string>();
expected.Add( "a" );
expected.Add( "b" );
expected.Add( "c" );
// Actual result
actual = new List<string>();
actual.Add( "a" );
actual.Add( "b" );
actual.Add( "c" );
// Verdict
Assert.IsTrue( actual == expected );
