title: Cannot convert .List<string> to string
body: <p>Not sure what I am doing wrong here. I selected date data from an sql server using the select statement below. I then wanted to add it to a list. I have checked the datatype using System.Type and it tells me the values I'm getting back are System.String. So I thought this should be able to add it to a list of type String but I keep getting the error:</p>
  
  <p>Cannot implicitly convert type <code>System.Collections.Generic.List&lt;string&gt;</code> to <code>string</code></p>
  
  <pre><code>public String getListFromColumnAsDATE(String columnName, String database)
  {
      myCommand = new SqlCommand("SELECT [Date] = convert(char(10), getdate(), 103) FROM Weekly_Tannery_Data", myConnection);
      List&lt;String&gt; graphList = new List&lt;String&gt;();
      myConnection.Open();
  
      myReader = myCommand.ExecuteReader();
  
      while (myReader.Read())
      {
          graphList.Add(myReader.GetString(0));
      }
  
      myConnection.Close();
      return graphList;
  }
  </code></pre>
