C#用GDAL创建SHP文件，升成的PRJ文件在ARCGIS中不识别的问题

在用GDAL创建SHP文件时，用SpatialReference类创建的坐标系统，在升成时会有一个PRJ文件，但是该文件在用ARCGIS不会被识别，原因为ARCGIS版本不一样所识别的文件也不一样）采用另外一种方法，直接升成PRJ文件，该文件必须要按照ASCII码升成，否则ARCGIS不识别
思路，用坐标取带号，该方法只对带上带号的2000高期吕克坐标系有用。

int dh = Convert.ToInt16(zb[0].X.ToString().Substring(0, 2));
string wkt = "PROJCS[\"CGCS2000 / 3-degree Gauss-Kruger zone"+dh.ToString() +"\"," +"GEOGCS[\"China Geodetic Coordinate System 2000\"," +"DATUM[\"China_2000\"," +"SPHEROID[\"CGCS2000\",6378137.0,298.257222101]]," + "PRIMEM[\"Greenwich\",0.0]," +"UNIT[\"Degree\",0.0174532925199433]]," +"PROJECTION[\"Gauss_Kruger\"]," +"PARAMETER[\"False_Easting\","+dh.ToString()+"500000.0]," +"PARAMETER[\"False_Northing\",0.0]," +"PARAMETER[\"Central_Meridian\","+(dh*3).ToString("F1")+"]," +"PARAMETER[\"Scale_Factor\",1.0]," +"PARAMETER[\"Latitude_of_Origin\",0.0]," +"UNIT[\"Metre\",1.0]]";string prjPath = zdPath + @"\ZD.prj";using (StreamWriter write = new StreamWriter(prjPath, false, Encoding.ASCII)){write.WriteLine(wkt);}

最重要是升成PRJ该文件必须是ASCII码升成，否则ARCGIS不会识别，以上代码在ARCGIS10.6中实测通过。
