How to populate a dataGridView with an array of user generated integers
提问by Foemilod
With this:
有了这个：
dataGridView.DataSource = theData.Select((x, index) =>
new { CreatureRoll = x, CreatureLabel = index}).OrderByDescending(x => x.CreatureRoll).ToList();
It produces the data correctly, But it produces all the rows in the array with extra data that will not be useful, empty data.
它正确地生成数据，但它生成数组中的所有行，其中包含额外的数据，这些数据不会有用，空数据。

You can use LINQ to generate the datasource from a array.
您可以使用 LINQ 从数组生成数据源。
int[] theData = new int[] { 14, 17, 5, 11, 2 };
dataGridView1.DataSource = theData.Where(x => x>0).Select((x, index) =>
new { RecNo = index + 1, ColumnName = x }).OrderByDescending(x => x.ColumnName).ToList();

Try this:
尝试这个：
int[] ints = new int[] { 1, 2, 3, 4, 5 };
gvMain.DataSource = ints;
gvMain.DataBind();
gvMainis a GridView, You can Add user generated array instead of ints.
gvMain是 GridView，您可以添加用户生成的数组而不是ints.

You can have code like this also,
你也可以有这样的代码，
dataGridView1.Columns.Add("Index", "Index");
dataGridView1.Columns.Add("Value", "Dice Value");
int[] theData = new int[] { 5, 2, 1, 5, 4, 1, 3, 1};
for (int i = 0; i < theData.Length; i++)
{
dataGridView1.Rows.Add(new object[] { i+1, theData[i] });
}
Output

Take a look at this .NET / C# Binding IList<string> to a DataGridView
看看这个.NET / C# Binding IList<string> to a DataGridView
Setting the datasource to an array will not display anything. Basically the values need to have a named property and need to implement IList to be able to be used as a DataSource. Something like this should do your bidding.
将数据源设置为数组将不会显示任何内容。基本上，这些值需要有一个命名属性，并且需要实现 IList 才能用作数据源。像这样的事情应该让你出价。
var array = new int[] { 3, 4, 4, 5, 6, 7, 8 };
dataGridView1.AutoGenerateColumns = true;
dataGridView1.DataSource = array.Select(x => new { IntValue = x }).ToList();

how to assign the collection for below situation:
如何为以下情况分配集合：
foreach (DataRow dr in dropDT.Rows)
{
values.Add(dr[0].ToString());
}
dataGridView1.Rows[e.RowIndex].Cells[4].Value = values;
dataGridView1.Rows[e.RowIndex].Cells[4].Value = values;
