我有一个 C# windows 窗体应用程序,我从打开文件浏览器将 XML 文件和 CGM 图形文件加载到我的应用程序中。我似乎可以一次选择几百个并且它可以正常工作,但是不再有一个对话框,告诉我它找不到文件这样的文件,但只给出了一半的文件名。我假设这是由于通过打开文件对话框一次可以选择/处理的文件数量受到限制。
有谁知道这个数字是多少,如果我一次选择超过这个限制,有没有办法解决它?
我有效地将文件“导入”到我的应用程序中,从而使用 foreach 循环将选定的文件移动到另一个文件夹,并且应用程序将导入的文件的所有文件名(以及其他数据)写入 XML 文件在文件上)。
下面是整个“导入”方法

int graphicsImported = 0;
if (projectName == "")
{
MessageBox.Show("Please open a project first", "DAWS");
return;
}
DialogResult result = openFileDialog1.ShowDialog();
if (result == DialogResult.OK)
{
MessageBox.Show("This process may take several minutes depending on the number of imports", "DAWS");
Application.UseWaitCursor = true;
foreach (string file in openFileDialog1.FileNames)
{
string fileName = Path.GetFileNameWithoutExtension(file); //Gets just the name from the file path
string ext = Path.GetExtension(file.ToLower());
if (ext != ".CGM" && ext != ".cgm")
{
bool exists = xmlFileWriter.checkIfFIleExists(fileName + ext);
if (exists != true)
{
xmlFileWriter.writeDatatoXML(file);
File.Move(file, CSDBpath + projectName + "\\CheckedIN\\" + fileName + ext);
DMsimported = DMsimported + 1;
}
else
{
MessageBox.Show(fileName + " already exists in the CSDB. This file will be skipped.", "DAWS");
}
}
else
{
if (File.Exists(CSDBpath + projectName + "\\Graphics\\" + fileName + ext))
{
if (Properties.Settings.Default.OverwriteGraphics == true)
{
File.SetAttributes(CSDBpath + projectName + "\\Graphics\\" + fileName + ext, FileAttributes.Normal); // need this line in order to set the file attributes. Exception thrown otherwise when system tries to overwrite the file.
File.Delete(CSDBpath + projectName + "\\Graphics\\" + fileName + ext);
File.Copy(file, CSDBpath + projectName + "\\Graphics\\" + fileName + ext); //need to give the option as to whether to delete the existing file or skipp.
