值类型“System.Data.SqlClient.SqlConnection”不能被转换为“1维阵列

Question

我试图用vb.net连接到SQL服务器，但我得到这个错误：

Value of type 'System.Data.SqlClient.SqlConnection' cannot be converted to '1-dimensional array of System.Data.SqlClient.SqlConnection'.

此是鳕鱼来源：

Imports System.Data.SqlClient 

Public Class Form1 

    Dim connection As SqlConnection() 
    Dim reader As SqlDataReader 


    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 
     Try 
      connection = New SqlConnection("data source=.; initial catalog=tp2_ado; integrated security = sspi") 
     Catch ex As Exception 
      MessageBox.Show(ex.Message()) 
     End Try 

    End Sub 
End Class

Imports System.Data.SqlClient 

Public Class Form1 

    Dim connection As SqlConnection ' this should not be an array ! 
    Dim reader As SqlDataReader 


    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 
     Try 
      connection = New SqlConnection("data source=.; initial catalog=tp2_ado; integrated security = sspi") 
     Catch ex As Exception 
      MessageBox.Show(ex.Message()) 
     End Try 

    End Sub 
End Class
