有人可以告诉我如何读取我的xml文件并将数据展平并将其插入sql数据库中合适的表中。提前谢谢。

Answer 1

在网上搜索，有很多关于您的要求的文章。试试这个：

Best way to load XML files to SQL Server using C#

和

Importing Large Xml Files to SQL Server Using SqlBulkCopy

Answer 2

首先，您必须解析XML并将其存储到自定义C＃对象中，或者您可以直接将XML传递给存储过程并在那里进行编码以将其保存到DB中。

将xml传递给存储过程并对其进行操作有点困难所以我建议在C＃中解析它然后获取自定义对象。一旦你得到它，你可以做任何你想做的事。

以下是我的文章，它准确地解释了您的需求。 Read XML file in ASP.NET(C#)

下面是解析XML文件并从中生成自定义C＃对象的示例代码。

public CatSubCatList GenerateCategoryListFromProductFeedXML()
{
    string path = System.Web.HttpContext.Current.Server.MapPath(_xmlFilePath);

    XDocument xDoc = XDocument.Load(path);

    XElement xElement = XElement.Parse(xDoc.ToString());


    List<Category> lstCategory = xElement.Elements("Product").Select(d => new Category
    {
        Code = Convert.ToString(d.Element("CategoryCode").Value),
        CategoryPath = d.Element("CategoryPath").Value,
        Name = GetCateOrSubCategory(d.Element("CategoryPath").Value, 0), // Category
        SubCategoryName = GetCateOrSubCategory(d.Element("CategoryPath").Value, 1) // Sub Category
    }).GroupBy(x => new { x.Code, x.SubCategoryName }).Select(x => x.First()).ToList();

    CatSubCatList catSubCatList = GetFinalCategoryListFromXML(lstCategory);

    return catSubCatList;
}
