C#的OpenFileDialog怎么用

Answer 1

        private void button1_Click(object sender, EventArgs e)
        {
            OpenFileDialog openFile = new OpenFileDialog();
            openFile.Filter = "Excel file|*.xls;*.xlsx|All file|*.*";  //打开文件过滤器
            openFile.Title = "打开文件";    //打开对话框标题
            if (openFile.ShowDialog() == DialogResult.OK)
            {
                this.textBox1.Text = openFile.FileName; //选择文件路径给textBox
            }
        }

 如果出现如下错误:

Attempting managed execution inside OS Loader lock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang.

请到Debug -> Exceptions-->Find, 输入查找LoaderLock,并将其勾选去掉
