大家好，今天继续分享我们的通用方法系列。

下面是今天的通用方法：

（1）这个通用方法为用文件流写数据

/// <summary>

        /// 用文件流写数据

        /// </summary>

        /// <param name="data"></param>

        /// <param name="savefilepath"></param>

        /// <param name="savefilename"></param>

        /// <returns></returns>

        public static string SavaProcess(string data, string savefilepath, string savefilename)

        {

            bool flag = !Directory.Exists(savefilepath);

            if (flag)

            {

                Directory.CreateDirectory(savefilepath);

            }

            string result = savefilepath + "\\" + savefilename;

            StreamWriter streamWriter = new StreamWriter(result, false);

            streamWriter.Write(data);

            streamWriter.Close();

            streamWriter.Dispose();

            return result;

        }

（2）这个通用方法为将datagridview转化为datatable

/// <summary>

        /// 将datagridview转化为datatable

        /// </summary>

        /// <param name="dgv"></param>

        /// <returns></returns>

        public DataTable GetDgvToTable(DataGridView dgv)//将datagridview转化为datatable

        {

            DataTable dt = new DataTable();

            for (int count = 0; count < dgv.Columns.Count; count++)

            {

                DataColumn dc = new DataColumn(dgv.Columns[count].Name);

                dt.Columns.Add(dc);

            }

            for (int count = 0; count < dgv.Rows.Count; count++)

            {

                DataRow dr = dt.NewRow();

                for (int countsub = 0; countsub < dgv.Columns.Count; countsub++)

                {

                    dr[countsub] = Convert.ToString(dgv.Rows[count].Cells[countsub].Value);

                }

                dt.Rows.Add(dr);

            }

            return dt;

        }

（3）这个通用方法为计算面积的方法

/// <summary>

    /// 计算面积的方法

    /// </summary>

    /// <param name="face"></param>

    /// <returns></returns>

    public static double Getfacearea(Tag face)//计算面积的方法

    {

        Face face1 = (Face)NXObjectManager.Get(face);

        NXOpen.Part workpart = theSession.Parts.Work;

        NXOpen.MeasureFaces measureFaces1;

        NXOpen.IParameterizedSurface[] facearea = new IParameterizedSurface[1];

        facearea[0] = face1;

        NXOpen.UnitCollection unicol = workpart.UnitCollection;

        NXOpen.Unit[] units1 = unicol.ToArray();//给一个单位做排序

        Unit unit1 = units1[1];//选择单位是毫米，还可以选择单位是米、厘米、英寸等单位

        measureFaces1 = workpart.MeasureManager.NewFaceProperties(unit1, unit1, 0.2, facearea);//给测量值一个新的属性

        double dis = measureFaces1.Area;      

        return dis;

    }

今天要分享的就是这么多，我们下篇文章再见。
