为什么会失败？

Question

“消息：声明。为真失败。预期：System.Collections.Generic.List1[...] but found System.Collections.Generic.List1 [...]”

我不知道为什么会失败。有人可以帮助我解决此错误吗]

        /// <summary>
        /// Test to Get the all the fee bands from Crm
        /// </summary>
        /// <returns>Response with a collection of ise_feeband entities</returns>
        [TestCategory("AnnualBillingService")]
        [TestMethod]
        public void GetFeeBandingListTest()
        
            List<ISE_feeband> fee_bands = new List<ISE_feeband>()  ;
            //fee_bands.Add(new ISE_feeband());           
            string entityname = "entity name";
            Guid ID = new Guid();

            using (ShimsContext.Create())
            
                //Arrange
                ShimCrmService.AllInstances.FetchString = ((@this, fetchXml) =>
                
                    return new Microsoft.Xrm.Sdk.EntityCollection()
                    
                        EntityName = entityname,
                        MoreRecords = true,
                        MinActiveRowVersion = "version",
                        PagingCookie = "paging cookie",
                        TotalRecordCount = 10,
                        TotalRecordCountLimitExceeded = false,
                    ;
                );

                //Act              
                var AnnualBillingService = new AnnualBillingService();
                var response = AnnualBillingService.GetFeeBandingList();

                //Assert
                Assert.IsNotNull(response, "Expected not-null response");
                Assert.IsTrue(response.FeeBands == fee_bands, "Expected: " + fee_bands + " but found " + response.FeeBands);
                foreach (var FeeBands in fee_bands)
                
                    Assert.IsTrue(FeeBands.Id == ID, "Expects True");
                
            
        
这里是代码。我无法理解该错误，奇怪的是，预期结果与实际结果相同，并且仍然出现错误。

“消息：Assert.IsTrue失败。预期：System.Collections.Generic.List1 [...]但找到System.Collections.Generic.List1 [...]”我不知道为什么会失败。谁能帮我解决这个错误...
