[英]Passing data from Excel Sheet to DataGridView using VB.NET
I am working on a project that aims to import and export data from a datagridview to excel table and viceversa. 我正在一个项目中,该项目旨在将数据从datagridview导入和导出到excel表,反之亦然。 So far, I managed to send data from my datagridview to excel, but I just can't do it from excel to datagrid... I tried the following code:
到目前为止,我设法将数据从datagridview发送到excel,但是我只是不能将数据从excel发送到datagrid ...我尝试了以下代码:
Dim dtSheet1 As New DataTable
Using cn As New System.Data.OleDb.OleDbConnection
Dim Builder As New OleDbConnectionStringBuilder With
{
.DataSource = filename,
.Provider = "Microsoft.ACE.OLEDB.12.0"
}
Builder.Add("Extended Properties", "Excel 16.0; IMEX=1;HDR=Yes;")
cn.ConnectionString = Builder.ConnectionString
cn.Open()
Using cmd As OleDbCommand = New OleDbCommand With {.Connection = cn}
cmd.CommandText = "SELECT * FROM [Sheet1$]"
Dim dr As System.Data.IDataReader = cmd.ExecuteReader
dtSheet1.Load(dr)
datagridview1.DataSource = dtSheet1
End Using
End Using
But I keep encountering the exception: (and I tried changing the target of my project from Any CPU to x64...) 但是我一直遇到异常:(并且我尝试将项目的目标从Any CPU更改为x64 ...)
An unhandled exception of type 'System.InvalidOperationException' occurred in System.Data.dll Additional information: The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.
System.Data.dll中发生了类型为'System.InvalidOperationException'的未处理异常。其他信息:Microsoft.ACE.OLEDB.12.0提供程序未在本地计算机上注册。
So: is there any way I could send data from excel to datagrid WITHOUT USING OLEDB? 所以:有什么方法可以不使用OLEDB而将数据从excel发送到datagrid? If so, I would be so grateful for a solution that could get me out of this, already working on this for 3 days...
如果是这样,我将非常感激能够让我摆脱困境的解决方案,并且已经为此工作了三天...
Have nice day! 祝你有美好的一天! (:

Actually this is even better: 实际上,这甚至更好:
'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine 未在本地计算机上注册“ Microsoft.ACE.OLEDB.12.0”提供程序
