c# - 将 specflow 表转换为字典

Question

我想从 c# specflow 表创建字典。我需要这个，因为标签中的值和每个特征文件的值都会发生变化。在我当前的特征文件中，我有 2 列。

And I submit with following 
| Label         | Value               |
| Namelabel     | texttoenter123      |
| Email         |test@test.com        |

对应步骤。尝试使用linq。

 [When(@"I submit with following ")]

   public void WhenISubmitWithFollowing(Table table)
        {
       //Should be something like this , which convert the table todictionary object
          var x = table.Rows.ToDictionary(k=>k.Keys,k=>k.Values);
        }``

目前我在这方面得到了空值。请帮忙。

如果您想灵活使用表格列标题:

var x = table.Rows.ToDictionary(r => r[0], r => r[1]);

否则:

var x = table.Rows.ToDictionary(r => r["Label"], r => r["Value"]);

如果你想要一个对 TechTalk.SpecFlow.Table 的快速扩展方法:

static class SpecFlowExtensions
{
    /// <summary>
    /// Converts a two column Gherkin data table to a dictionary
    /// </summary>
    /// <param name="table"></param>
    /// <returns></returns>
    public static Dictionary<string, string> ToDictionary(this Table table)
    {
        if (table == null)
            throw new ArgumentNullException(nameof(table));

        if (table.Rows.Count == 0)
            throw new InvalidOperationException("Gherkin data table has no rows");

        if (table.Rows.First().Count != 2)
            throw new InvalidOperationException($@"Gherkin data table must have exactly 2 columns. Columns found: ""{string.Join(@""", """, table.Rows.First().Keys)}""");

        return table.Rows.ToDictionary(row => row[0], row => row[1]);
    }
}

并使用扩展方法:

var data = table.ToDictionary();
