c# 调用 surfer

1. 引用surfer安装后自动添加的com组件

2. 代码调用

using Surfer;


Application app = new Application();
var path = AppDomain.CurrentDomain.BaseDirectory;
app.GridData2(DataFile: path + "data.dat",            //数据文件地址
    xCol: 1,                                        //x为第一列数据
    yCol: 2,                                        //y为第二列数据
    zCol: 3,                                        //z为第三列数据
    DupMethod: Surfer.SrfDupMethod.srfDupNone,
    xMin: 117.742635,                                //x最小值
    xMax: 122.452486,                                //x最大者
    yMin: 29.418809,                                //y最小值
    yMax: 32.463007,                                //y最大值
    Algorithm: Surfer.SrfGridAlgorithm.srfKriging,    //插值算法Kriging
    NumCols: (122.452486 - 117.742635) / 0.01,        //x方向插值数据量
    NumRows: (32.463007 - 29.418809) / 0.01,        //y方向插值数据量
    OutGrid: path + "grid.grd",                        //返回文件为gridfile
    OutFmt: Surfer.SrfGridFormat.srfGridFmtAscii);    //返回文件编码为Ascii
app.Quit();
System.GC.Collect(System.GC.GetGeneration(app));
