您可以

诺塔尝试：

调整您的查询

调整你的参数值（字节）

调整你的连接

 Dim connetionString As String 
     Dim connection As SqlConnection 
     Dim adapter As New SqlDataAdapter 
     Dim sql As String 

     connetionString = "......." 
     connection = New SqlConnection(connetionString) 

     sql = "...." 
     Try 
      connection.Open() 

      Dim cmd As New SqlCommand(sql, connection) 
      cmd.Parameters.Add("@Name", SqlDbType.VarBinary) 

      Dim image As [Byte]() 
      cmd.Parameters("@Name").Value = image 

      adapter.InsertCommand = cmd 
      adapter.InsertCommand.ExecuteNonQuery() 
      MsgBox("Image inserted !! ") 

     Catch ex As Exception 
      ...... 
     End Try
