SpecFlow功能文件错误 - 对象必须实现IConvertible

Question

我在VS 2107中的特征文件中的一个步骤中的SpecFlow（2.1.o）中出现以下错误。它应该与SpecFlow框架问题有关吗？

但我在其他功能中没有此错误。他们工作正常。

XXXXfeature.cs文件中的错误：

Answer 1

错误的原因是[StepArgumentTransformation] public IList<MovesStaging> TransformMovesStaging(Table identifiers) { return identifiers.Rows.Select(row => new MovesStaging { PartitionKey = ParseTableRowFieldAsString(row, "PartitionKey"), RowKey = ParseTableRowFieldAsString(row, "RowKey"), Timestamp = ParseTableRowFieldAsTimeStampUtc(row, "Timestamp"), Status = ParseTableRowFieldAsString(row, "Status"), ExpiryDate = ParseTableRowFieldAsDateTimeUtc(row, "ExpiryDate") }).ToList(); } 。如下。

var _array = [
{name:"sample1" ,date:'08-07-2017'}, 
{name:"sample2" ,date:'08-07-2017'},
{name:"sample3" ,date:'08-08-2017'},
{name:"sample4" ,date:'08-09-2017'},
{name:"sample5" ,date:'08-09-2017'},
{name:"sample5" ,date:'08-09-2017'}
];

var regrouped = [];

for (var i = 0; i < _array.length; i++) {
  var addNew = true;
  for (var j = 0; j < regrouped.length; j++) {
    if (_array[i].date === regrouped[j][0].date) {
      regrouped[j].push(_array[i]);
      addNew = false;
    }
  }
  if (addNew) {
    regrouped.push([_array[i]]);
  }
}

console.log(regrouped);

基本上，每当您尝试通过要素文件插入数据时，您都需要这样做。 之后我遇到了类似的question类型。我可能因为这个问题而错过了这个问题。
