窗体移动API:需要引用命名空间
//窗体移动API [DllImport("user32.dll")] public static extern bool ReleaseCapture(); [DllImport("user32.dll")] public static extern bool SendMessage(IntPtr hwnd, int wMsg, int wParam, int IParam); public const int WM_SYSCOMMAND = 0x0112; public const int SC_MOVE = 0xF010; public const int HTCAPTION = 0x0002; [DllImport("user32")] private static extern int SendMessage(IntPtr hwnd, int wMsg, int wParam, IntPtr lParam); private const int WM_SETREDRAW = 0xB; private void Form1_MouseDown(object sender, MouseEventArgs e) { if (this.WindowState == FormWindowState.Normal) { ReleaseCapture(); SendMessage(this.Handle, WM_SYSCOMMAND, SC_MOVE + HTCAPTION, 0); } }
窗体阴影API:在构造函数中加一句话
//窗体阴影API const int CS_DropSHADOW = 0x20000; const int GCL_STYLE = (-26); [DllImport("user32.dll", CharSet = CharSet.Auto)] public static extern int SetClassLong(IntPtr hwnd, int nIndex, int dwNewLong); [DllImport("user32.dll", CharSet = CharSet.Auto)] public static extern int GetClassLong(IntPtr hwnd, int nIndex); public Form1() { InitializeComponent(); SetClassLong(this.Handle, GCL_STYLE, GetClassLong(this.Handle, GCL_STYLE) | CS_DropSHADOW); }
1.colordialog:颜色对话框 改变对话框的字体颜色
private void 自定义CToolStripMenuItem_Click(object sender, EventArgs e) { DialogResult dr = colorDialog1.ShowDialog(); if (dr == DialogResult.OK) { richTextBox1.ForeColor = colorDialog1.Color; } }
2.fontdialog:字体对话框
private void 选项OToolStripMenuItem_Click(object sender, EventArgs e) { DialogResult dr = fontDialog1.ShowDialog(); if (dr == DialogResult.OK) { richTextBox1.Font = fontDialog1.Font; } }
showapply:是否显示应用按钮
showcolor:是否显示颜色按钮
要设置字体颜色,在if中再加上:
richtextbox.forecolor=fontdialog.color;
3.folderbrowserdialog:文件路径
private void button2_Click(object sender, EventArgs e) { DialogResult dr= folderBrowserDialog1.ShowDialog(); if (dr == DialogResult.OK) { richTextBox1.Text = folderBrowserDialog1.SelectedPath; } }
4.openfiledialog:打开文件
使用流需要应用命名空间:
using System.IO;
private void button2_Click(object sender, EventArgs e) { openFileDialog1.Filter = "文本文件|*.txt";//设置打开格式 DialogResult dr= openFileDialog1.ShowDialog(); if (dr == DialogResult.OK) { label1.Text = openFileDialog1.FileName;//显示文件路径名 StreamReader sr = new StreamReader(openFileDialog1.FileName,Encoding.Default);//防止乱码 richTextBox1.Text= sr.ReadToEnd(); } }
5.savefiledialog:保存文件
private void button3_Click(object sender, EventArgs e) { saveFileDialog1.Filter = "文本文件|*.txt|word|*.doc"; DialogResult dr = saveFileDialog1.ShowDialog(); if (dr == DialogResult.OK) { StreamWriter sw = new StreamWriter(saveFileDialog1.FileName,false,Encoding.Default);//防止乱码 sw.Write(richTextBox1.Text); sw.Flush(); } }
