Tucao about our school, I feel that the teachers always think that we can be self-taught. I didn't mention GDAL (could it be that the teacher mentioned it, but I didn't listen carefully in class???), I didn't find this library until I encountered a bottleneck in my homework and looked for information. After collecting a lot of information, I finally installed and configured it for a long time. All right. . .

My computer: WIN10, VS2015, 64 bit
Step 1: Download GDAL
Official website: http://trac.osgeo.org/gdal/wiki/DownloadSource
I downloaded 2.2.3
After decompression, put it in a GDAL folder I created in the D drive, the path is D:\GDAL
Step 2: Download swigwin (note that it is swigwin, don't download it wrong)
This is used for C# compilation of gdal. If you do not use C#, this step can be ignored
Download the official website: https://sourceforge.net/projects/swig/files/swigwin/
I downloaded swigwin3.0.12 and put it in the path D:\GDAL
Step 3: Make Various Modifications
Open the gdal-2.2.3 folder, find nmake.opt, open it with a text editor, I use notepad++
(1) Find GDAL_HOME and modify the path
Oh I see:
Change it to this: (a new gdal2.23 folder is created in the GDAL folder, and the compiled files are here)
(2) Find the red box below
Change it to:
Step 3: Compile
(1) Enter the vs2015 developer command prompt
(2) Enter cmd, enter cd D:\GDAL\gdal-2.2.3, and enter the path of the previously downloaded gdal
Then enter nmake /f makefile.vc
After this step is successful, enter nmake /f makefile.vc install
After this step is successful, enter: nmake /f makefile.vc devinstall
After the above three commands are successfully executed, the following folders will appear in the D:\GDAL\gdal2.23 folder:
Up to now, the compilation has actually been completed, but I want to use C#, so I need to compile the following
Step 4: Compile C#
(1) Open D:\GDAL\gdal-2.2.3, find nmake.opt (the file that was compiled before), and find SWIG=swig.exe
Change it to the following (the storage path of the previously downloaded swigwin file)
(2) Open D:\GDAL\gdal-2.2.3\swig\csharp\AssemblyInfo.cs file
Find line 94 and comment out this line
（3）打开D:\GDAL\gdal-2.2.3\swig\csharp\gdal\GdalPINVOKE.cs
D:\GDAL\gdal-2.2.3\swig\csharp\ogr\OgrPINVOKE.cs
D:\GDAL\gdal-2.2.3\swig\csharp\osr\OsrPINVOKE.cs
Modify lines 188~193: Comment out the repeated code to solve the problem of interface redefinition.
(The following is one of them, all three are modified like this)
（4）D:\GDAL\gdal-2.2.3\swig\csharp\gdal\Band.cs|Dataset.cs|Driver.cs，修改第17行，解决接口成员名错误问题。
public Band(IntPtr cPtr, bool cMemoryOwn, object parent) : base(GdalPINVOKE.Band_SWIGUpcast(cPtr), cMemoryOwn, parent)
public Dataset(IntPtr cPtr, bool cMemoryOwn, object parent) : base(GdalPINVOKE.Dataset_SWIGUpcast(cPtr), cMemoryOwn, parent)
public Driver(IntPtr cPtr, bool cMemoryOwn, object parent) : base(GdalPINVOKE.Driver_SWIGUpcast(cPtr), cMemoryOwn, parent)
（5）上面的修改完成后，回到cmd里，进入D:\GDAL\gdal-2.2.3\swig\csharp之下
依次执行命令：nmake /f makefile.vc
nmake /f makefile.vc install
等编译成功后，D:\GDAL\gdal2.23 文件夹里会出现csharp文件夹，csharp文件夹里有8个.dll文件。
至此，gdal的C#就编译成功了。
------------------------------------------------------------------------------------------------------------------------------
下面是在VS2015里进行配置。
1、新建一个窗体文件
2、在引用里添加D:\GDAL\gdal2.23\csharp里的四个 _csharp.dll 类型的引用
3、将D:\GDAL\gdal2.23\csharp里除了_csharp.dll类型的其余的.dll文件，加上D:\GDAL\gdal2.23\bin里的 gdal202.dll 复制到刚刚建立的窗体文件的bin/Debug文件夹里去。（一层层文件夹找就行）
4、代码示例
就运行成功了，撒花完结
CSDN的用户体验真的是极差极差极差!!!代码经常串行，动不动就崩!!!
