復制代碼 代碼如下:

/// <summary>
/// 合并兩個相同的DataTable,返回合并后的結果
/// </summary>
/// <param></param>
/// <param></param>
/// <returns></returns>
public DataTable CombineTheSameDatatable(DataTable dt1, DataTable dt2)
{
if (dt1.Rows.Count == 0 && dt2.Rows.Count == 0)
{
return new DataTable();
}
if (dt1.Rows.Count == 0)
{
return dt2;
}
if (dt2.Rows.Count == 0)
{
return dt1;
}
DataSet ds = new DataSet();
ds.Tables.Add(dt1.Copy());
ds.Merge(dt2.Copy());
return ds.Tables[0];
}
