以下是我写的读写 XML 共通参考下

public class MCHBaseClass
{
private DataSet ds = new DataSet();
private string mPath = "";

public DataSet getDS()
{
return ds;
}

/// <summary>
/// 加载获取的MXL 获取XML路径
/// </summary>
/// <param name="path"> </param>
public void LoadSetting(string path)
{
this.mPath = path;
this.ds = new DataSet();

try
{
ds.ReadXml(@mPath);
}
catch (Exception ex)
{
System.Console.WriteLine(ex.Message);
throw;
}
}

public DataTable Getting(string fNode)
{
DataTable dt = new DataTable();

try
{
dt = ds.Tables[fNode];
return dt;

}
catch (Exception ex)
{
System.Console.WriteLine(ex.Message);
throw;

}
}

/// <summary>

/// <returns> </returns>
public string Getting(string fNode, int intKey, string strSection)
{
string strValue = "";

try
{
strValue = Convert.ToString(ds.Tables[fNode].Rows[intKey][strSection]);
return strValue;

}
catch (Exception ex)
{
System.Console.WriteLine(ex.Message);
throw;

}
}

/// <summary>

public void SaveSettings(DataSet ds1, string mPath1)
{
try
{
ds1.WriteXml(@mPath1);
}
catch (Exception ex)
{
System.Console.WriteLine(ex.Message);
throw;
}
}

/// <summary>

public void SetSetting(string fNode, int intKey, string strSection, string strDefaultValue)
{
try
{

ds.AcceptChanges();
this.SaveSettings(ds,mPath);

}

{
try
{

ds.AcceptChanges();
this.SaveSettings(ds, mPath);
}
catch (Exception ex)
