我發生錯誤時的環境:Windows 7,Framework 4、0,Microsoft Office 2007,VS2010,c# WinForm;部分代碼:
string strConn = "Provider=Microsoft.Ace.OleDb.12.0;Persist Security Info=False;" + "data source=" + @excelPath + ";Extended Properties='Excel 12.0; HDR=yes; IMEX=2'";
OleDbConnection conn = new OleDbConnection();
conn.ConnectionString = strConn;
try
{
OleDbCommand cmd = null;
try
{
cmd = new OleDbCommand("Insert Into [Sheet1$] Values('abc', 'bac', '0', '123456', 'test','測試','aa')", conn);//(A,B,C,D,E,F,G)
cmd.ExecuteNonQuery();
}
catch (System.Exception ex)
{
textBox1.Text += ("插入數據失敗:" + ex.Message);
textBox1.Text += ("\r\n");
}遇到此錯誤的時候第一想到的就是沒有權限,但使用管理員身份運行依然是相同的錯誤!又通過以下代碼添加權限,還是一樣的錯誤:FileInfo fi = new FileInfo(excelPath);
System.Security.AccessControl.FileSecurity fileSecurity = fi.GetAccessControl();
fileSecurity.AddAccessRule(new FileSystemAccessRule("Everyone", FileSystemRights.FullControl, AccessControlType.Allow));
fileSecurity.AddAccessRule(new FileSystemAccessRule("Users", FileSystemRights.FullControl, AccessControlType.Allow));
fi.SetAccessControl(fileSecurity);
DirectoryInfo di = new DirectoryInfo(Path.GetDirectoryName(excelPath));
System.Security.AccessControl.DirectorySecurity dirSecurity = di.GetAccessControl();
dirSecurity.AddAccessRule(new FileSystemAccessRule("Everyone", FileSystemRights.FullControl, AccessControlType.Allow));
dirSecurity.AddAccessRule(new FileSystemAccessRule("Users", FileSystemRights.FullControl, AccessControlType.Allow));
di.SetAccessControl(dirSecurity);知識補習,這裡的連接字符串多了:Extended Properties='Excel 12.0; HDR=yes; IMEX=2'參數HDR的值:
HDR=Yes,這代表第一行是標題,不做為數據使用 ,如果用HDR=NO,則表示第一行不是標題,做為數據來使用。系統默認的是YES
