我试图在.net中创建程序,使用C#上传excel文件,读取它,并从excel数据中将excel文件添加到server数据库中。在这样做的时候,我得到了一个错误:无法找到可安装的ISAM?
有人能帮我解决这个问题吗?
或者可以提供一些样例代码,以不同的方式来完成这样的任务?
protected void Button1_Click(object sender, EventArgs e)
{
String excelConnectionString1;
String fname = FileUpload1.PostedFile.FileName;
if (FileUpload1.PostedFile.FileName.EndsWith(".xls"))
{
String excelsheet;
FileUpload1.SaveAs(Server.MapPath("~/file/" + FileUpload1.FileName));
if (FileUpload1.PostedFile.FileName.EndsWith(".xls"))
{
excelConnectionString1 = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Server.MapPath("~/file/" + FileUpload1.FileName) + ";Extended Properties=Excel 8.0;HDR=Yes;";
OleDbConnection myEcelConnection1 = new OleDbConnection(excelConnectionString1);
myEcelConnection1.Open();
if (txtsheet.Text.Length == 0)
{
lblmsg.Text = "Please Write File Name";
}
else
{
excelsheet = "[" + txtsheet.Text + "$" + "]";
string sheet = "Select * from [" + txtsheet.Text + "$" + "]";
OleDbCommand cmd1 = new OleDbCommand(sheet, myEcelConnection1);
cmd1.CommandType = CommandType.Text;
OleDbDataAdapter myAdapter1 = new OleDbDataAdapter(cmd1);
DataSet myDataSet1 = new DataSet();
myAdapter1.Fill(myDataSet1);
int a = myDataSet1.Tables[0].Rows.Count - 1;
string name;
string dob;
for (int i = 0; i <= a; i++)
{
name = myDataSet1.Tables[0].Rows[i].ItemArray[0].ToString();
dob = myDataSet1.Tables[0].Rows[i].ItemArray[1].ToString();
SqlConnection con = new SqlConnection("Connection String for Sql Server");
con.Open();
SqlCommand command = new SqlCommand("Insert into info(name,dob)values(@valname,@valdob)", con);
command.Parameters.Add("@valname", SqlDbType.VarChar, 50).Value = name;
command.Parameters.Add("@valdob", SqlDbType.VarChar, 50).Value = dob;
command.CommandType = CommandType.Text;
SqlDataAdapter da = new SqlDataAdapter(command);
DataSet ds = new DataSet();
da.Fill(ds);
con.Close();
}
}
}
}
}
}}

Jet驱动程序没有64位版本,因此如果您在64位操作系统上运行此驱动程序,您可能需要在您的x86应用程序中针对.NET,而不是任何CPU。

当连接字符串的语法不正确时,也会生成此错误。这通常发生在使用多个扩展属性参数时。以下是一个例子:
ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=e:\My Documents\Book20.xls;Extended Properties=""Excel 12.0;HDR=NO;IMEX=1"""像这样更改连接字符串
ConnectionString=" Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\NAVEEN KUMAR\DOTNET\windows\WindowsApplication1\WindowsApplication1\123.xls;Excel 12.0 Xml;HDR=YES"https://stackoverflow.com/questions/16233669
