DataSet.DataTable.DataRow（单个）到XML字符串 [英] DataSet.DataTable.DataRow (Single) to XML String

问题描述

我当前正在处理的项目中有强类型的数据集，我需要将DataRow对象从DataSet（DataSet中只有1个DataTable）转换为XML字符串。我尝试了以下尝试，但完全失败：

I have strongly-typed datasets in the project that I am currently working on and I need to convert a DataRow object from the DataSet (only 1 DataTable in the DataSet) to an XML string. I attempted the following with only utter failure:

string originalXmlString = string.Empty;

DataSet ds = new DataSet();

ds.Tables.Add(this.ObjectDataRow.Table);
ds.Tables[0].ImportRow(this.ObjectDataRow);

using (StringWriter sw = new StringWriter())
{
    ds.Tables[0].WriteXml(sw);                         
    originalXmlString = sw.ToString();
}

req.OriginalDataRow = originalXmlString;

任何帮助将不胜感激！

谢谢，
基思（Keith）

推荐答案

在MSDN页面上，关于<一个href = http://msdn.microsoft.com/zh-cn/library/system.data.datatable.clone.aspx rel = nofollow noreferrer> Clone（）函数。

I was able to figure it out with the assistance of a MSDN page regarding the Clone() function.

下面的代码经过修改并可以很好地工作：

The following code is revised and works great:

string originalXmlString = string.Empty;

DataSet ds = new DataSet();

//ds.Tables.Add(this.ObjectDataRow.Table);

ds.Tables.Add(this.ObjectDataRow.Table.Clone());

ds.Tables[0].ImportRow(this.ObjectDataRow);

using (StringWriter sw = new StringWriter())
{
    ds.Tables[0].WriteXml(sw);                         
    originalXmlString = sw.ToString();
}

req.OriginalDataRow = originalXmlString;
