LINQ:自定义列名 [英] LINQ: custom column names
问题描述
更新
我基本上绑定查询一个WinForms DataGridView的。我想列标题是适当的,必要时有空格。例如,我想列标题为名字代替的姓
你如何创建LINQ自己的自定义列名?
例如:
昏暗的查询=从u在db.Users _
选择u.FirstName AS'名'
我解决我自己的问题,但所有的答案都非常有帮助,并指出我朝着正确的方向。
在我的LINQ查询,如果列名有多个单词我会用下划线分开的话:
昏暗的查询=从u在用户_
SELECT名字= u.FirstName
然后,在油漆中 DataGridView的方法,我换成了空间的标题中的所有下划线:
私人小组DataGridView1_Paint(BYVAL发件人为对象,BYVAL E上System.Windows.Forms.PaintEventArgs)处理DataGridView1.Paint
对于每个C作为的DataGridViewColumn在DataGridView1.Columns
c.HeaderText = c.HeaderText.Replace(_,)

结束小组
UPDATE
I'm basically binding the query to a WinForms DataGridView. I want the column headers to be appropriate and have spaces when needed. For example, I would want a column header to be First Name instead of FirstName.
How do you create your own custom column names in LINQ?
For example:
Dim query = From u In db.Users _
Select u.FirstName AS 'First Name'
I solved my own problem but all of your answers were very helpful and pointed me in the right direction.
In my LINQ query, if a column name had more than one word I would separate the words with an underscore:
Dim query = From u In Users _
Select First_Name = u.FirstName
Then, within the Paint method of the DataGridView, I replaced all underscores within the header with a space:
Private Sub DataGridView1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles DataGridView1.Paint
For Each c As DataGridViewColumn In DataGridView1.Columns
c.HeaderText = c.HeaderText.Replace("_", " ")
Next
End Sub
