我还测试了上面提到的过滤器。当我浏览...和显示所有文件时,它没有显示任何过滤器。我需要的是,当单击“浏览”按钮时,只有XLSX或XLS文件显示给用户。
提前致谢
那是因为在设置过滤器和FilterIndex之前先显示对话框。
您的代码应该像
openFileDialog1.Filter = "Excel |*.xlsx"; //"Excel Files|(*.xlsx, *.xls)|*.xlsx;*.xls";
openFileDialog1.FilterIndex = 1;
DialogResult result = openFileDialog1.ShowDialog(); // Show the dialog.
