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。
