DataTable 整行为空时，去除空行,常用于Excel导入，转换为DataTable时出现

protected void RemoveEmpty(DataTable dt)
{
List<DataRow> removelist = new List<DataRow>();
for (int i = 0; i < dt.Rows.Count; i++)
{
bool IsNull = true;
for (int j = 0; j < dt.Columns.Count; j++)
{
if (!string.IsNullOrEmpty(dt.Rows[i][j].ToString().Trim()))
{
IsNull = false;
}
}
if (IsNull)
{
removelist.Add(dt.Rows[i]);
}
}
for (int i = 0; i < removelist.Count; i++)
{
dt.Rows.Remove(removelist[i]);
}
}
