Single出来的数据为什么在dataGridView 不显示?

[sugarbelle]

  var v = dc.baobao.Single(q => q.huohao=="1361");

    dataGridView1.DataSource = v;

调试的时候看到v已经有baobao完整表.但是dataGridView1不显示.
要怎么做才显示呢?

DataTable dt=v; 报错,不能转换

Single没有.ToList()方法.
Where不用.ToList()直接可以显示..哎

仔细看看3楼你就明白了

你把它转换成一个datatable看看

[南山行者]

var v = dc.baobao.Single(q => q.huohao=="1361");
DataTable dt=v;
dataGridView1.DataSource = dt;

因为dataGridView的数据源和表是能对应的，而你的var格式使得dataGridView1对应不了字段和值

public Object DataSource { get; set; }

The IList interface, including one-dimensional arrays.

The IListSource interface, such as the DataTable and DataSet classes.

The IBindingList interface, such as the BindingList<T> class.

The IBindingListView interface, such as the BindingSource class.

Single返回的是一个实体

var v = dc.baobao.Where(q => q.huohao=="1361").ToList();

dataGridView1.DataSource = v;
