1.新建地图文档
public IMapDocument pMapDoc;
private void TSMenuItem_New_Click(object sender, EventArgs e)
{
pMapDoc = new MapDocumentClass();
//设置默认路径
string filePath = Application.StartupPath + "\\Temp\\Untitled.mxd";
pMapDoc.New(filePath);
pMapDoc.Open(filePath, "");
//空白的地图文件只有一个地图
axMapControl1.Map = pMapDoc.get_Map(0);
MessageBox.Show("新建地图文档成功！");
}
2.打开地图文档
private void TSMenuItem_Open_Click(object sender, EventArgs e)
{
OpenFileDialog openFileDialog = new OpenFileDialog();
openFileDialog.Filter = "Map Documents(*.mxd)|*.mxd";
if(openFileDialog.ShowDialog()==DialogResult.OK)
{
第一种方式
string fileName = Path.GetFileName(filePath);
if (axMapControl1.CheckMxFile(fileName))
{
axMapControl1.MousePointer = esriControlsMousePointer.esriPointerHourglass;
axMapControl1.LoadMxFile(fileName, 0, Type.Missing);
axMapControl1.MousePointer = esriControlsMousePointer.esriPointerDefault;
}
else
{
MessageBox.Show("所选文件不是地图文档文件！", "信息提示");
return;
}
第二种方式
pMapDoc = new MapDocumentClass();
pMapDoc.Open(filePath,"");
for(int i=0;i<pMapDoc.MapCount;i++)
{
axMapControl1.Map=pMapDoc.get_Map(i);
}
axMapControl1.ActiveView.Refresh();
}
}
3.保存地图文档
3.1 用于自定义IMapDocument接口打开地图文档时
private void TSMenuItem_Save_Click(object sender, EventArgs e)
{
//如何pMapDoc为空，取消保存
if (pMapDoc == null) return;
if (pMapDoc.get_IsReadOnly(pMapDoc.DocumentFilename))
{
MessageBox.Show("地图文档是只读的，不能保存！");
return;
}
//根据相对路径保存文档
pMapDoc.Save(pMapDoc.UsesRelativePaths, true);
MessageBox.Show("地图文档保存成功！");
}
3.2 用于使用AE内置方式打开地图文档时（快捷方式打开）
private void TSMenuItem_Save_Click(object sender, EventArgs e)
{
IMxdContents pMxdC = axMapControl1.Map as IMxdContents;
IMapDocument pMapDoc= new MapDocumentClass();
pMapDoc.Open(axMapControl1.DocumentFilename, "");
pMapDoc.ReplaceContents(pMxdC);
if (pMapDoc== null) return;
if (pMapDoc.get_IsReadOnly(pMapDoc.DocumentFilename))
{
MessageBox.Show("地图文档是只读的，不能保存！");
return;
}
pMapDoc.Save(pMapDoc.UsesRelativePaths, true);
MessageBox.Show("地图文档保存成功!");
}
3.3 用于使用AE内置方式添加数据时（快捷方式添加数据）
private void TSMenuItem_Save_Click(object sender, EventArgs e)
{
IMxdContents pMxdC = axMapControl1.Map as IMxdContents;
IMapDocument pMapDoc= new MapDocumentClass();
//设置保存路径
string filePath = Application.StartupPath + "\\Temp\\Untitled.mxd";
pMapDoc.New(filePath);
pMapDoc.ReplaceContents(pMxdC);
pMapDoc.Save(true, true);
MessageBox.Show("地图文档保存成功!");
}
4.另存地图文档
private void TSMenuItem_SaveAs_Click(object sender, EventArgs e)
{
SaveFileDialog saveFileDialog = new SaveFileDialog();
saveFileDialog.Title = "另存为";
saveFileDialog.FileName = "Untitled";
saveFileDialog.DefaultExt = "mxd";
saveFileDialog.Filter = "Map Documents(*.mxd)|*.mxd";
if (saveFileDialog.ShowDialog() == DialogResult.OK)
{
string filePath = saveFileDialog.FileName;
pMapDoc = new MapDocumentClass();
pMapDoc.New(filePath);
pMapDoc.Open(filePath,"");
pMapDoc.Save(pMapDoc.UsesRelativePaths, true);
MessageBox.Show("地图文档另存成功!");
}
}
