问题描述
嗨
我想用linq对象填充数据集到示例在Microsoft的网站中:
example
'填写数据集。
Dim ds As New DataSet()
ds.Locale = CultureInfo.InvariantCulture
'请参阅将数据加载到DataSet主题中的FillDataSet方法。
FillDataSet(ds)
Dim products As DataTable = ds.Tables(Product)
Dim query = From product in products inAsEnumerable()_
选择product.Field(Of String)(Name)
Console.WriteLine(Product Names:)
For each productName in query
Console.WriteLine (productName)
下一步
FillDataSet(ds)没有实现源代码?应该是什么代码?
或
如何填充数据集因为所有的例子都是FillDataSet没有在linq中实现这个方法?
解决方案
' 填充DataSet。
Dim ds As New DataSet()
ds.Locale = CultureInfo.InvariantCulture
'请参阅中的FillDataSet方法将数据加载到DataSet主题中。
FillDataSet(ds)
Dim products As DataTable = ds.Tables( 产品)
Dim query = From product In products.AsEnumerable()_
选择产品
Console.WriteLine( 产品名称:)
For Each p In query
Console.WriteLine(p.Field(Of 字符串)( 名称))
下一步

Hi
I want to fill dataset using linq object to the example In Microsoft's site:
example
' Fill the DataSet. Dim ds As New DataSet() ds.Locale = CultureInfo.InvariantCulture ' See the FillDataSet method in the Loading Data Into a DataSet topic. FillDataSet(ds) Dim products As DataTable = ds.Tables("Product") Dim query = From product In products.AsEnumerable() _ Select product.Field(Of String)("Name") Console.WriteLine("Product Names:") For Each productName In query Console.WriteLine(productName) Next
The FillDataSet (ds) did not implement the source? What was the code should be?
or
