从XML文件读入数据集

Question

I try to fill a DataSet with values from a XML file like this so I can then fill a DataGridView with the values:

DataSet ds = new DataSet();
ds.ReadXml(@"C:\aaa.xml");
dataGridView1.DataSource = ds;
dataGridView1.DataSource = "Products";

But I don't get anything. What am I doing wrong?

Answer 1

Are you sure your data loaded will be called Products in your data set??

Try to verify by inspecting the tables in the dataset after you've loaded the data:

DataSet ds = new DataSet();
ds. ReadXml(@"C:\aaa.xml");

foreach(DataTable t in ds.Tables)
{
   string tableName = t.TableName;   // put a breakpoint here - inspect the table names
}

If you want to use simply show the first table loaded, try this snippet:

DataSet ds = new DataSet();
ds. ReadXml(@"C:\aaa.xml");

dataGridView1.DataSource = ds;
dataGridView1.DataMember = ds.Tables[0].TableName;

Answer 2

DataSet ds = new DataSet();
ds.ReadXml(@"C:\aaa.xml");
dataGridView1.DataSource = ds;
dataGridView1.Datamember= "Products";
