Question

我有一个包含日期和版本的XML文件。像这样的时间

  <date>3/24/2014</date>
  <time>9:00 AM</time>
</playdate>

我将这些数据存储在数据集＆amp;想要添加数据表。我写这个代码来获取数据

                DataRow dr = dt.NewRow();
                dr["StartDate"] = ds.Tables[0].Rows[i][1].ToString();
                dr["StartTime"] = ds.Tables[0].Rows[i][1].ToString();

但问题是当我在excel文件中导出数据时我得到了date＆amp;在同一列的excel文件中的时间。我想在我的StartDate＆amp;在StartTime中的时间。我该如何分割XML数据

        string input = reader.ReadToEnd();

        input = input.Replace("- <", " <");
        input = input.Replace(" & ", " &#38; ");
        input = input.Replace("W&W", "W&#38;W");

Answer 1

您在 StartDate 和 StartTime 中访问相同的单元格值。很可能下一个细胞应该给你时间价值。

您也可以格式化与XML中指定相同的日期时间，例如（MM / DD / YYYY）时间小时分和秒也是如此。

请参阅此处的代码示例：

string sDate = ds.Tables[0].Rows[i][0].ToString();
string sTime = ds.Tables[0].Rows[i][1].ToString();  
DateTime dDateTime;     
DataRow dr = dt.NewRow();
//cond: for checking the datetime parsing
if (DateTime.TryParseExact(sDate, "M/dd/yyyy", CultureInfo.InvariantCulture, DateTimeStyles.None, out dDateTime))
{   
    //sDate  = dDateTime.ToString("M/dd/yyyy");
    //dr["StartDate"] = sDate;  
            dr["StartDate"] = dDateTime;
}   
//cond: for checking the datetime parsing
if (DateTime.TryParseExact(sTime, "hh:mm:ss", CultureInfo.InvariantCulture, DateTimeStyles.None, out dDateTime))
{   
    //sTime  = dDateTime.ToString("h:mm:ss");
    //dr["StartTime"] = sTime;
              dr["StartTime"] = dDateTime;  
}

Answer 2

尝试使用DateTime.ParseExact

string cellValue = "3/31/2014 9:00:00 AM";// this can be a cell value from excel file like ds.Tables[0].Rows[i][1].ToString()
DateTime date = DateTime.ParseExact(
            cellValue, 
            "M/dd/yyyy h:mm:ss tt", 
            CultureInfo.InvariantCulture);

string startDate  = date.ToString("M/dd/yyyy");
string startTime  = date.ToString("h:mm:ss tt");
