两个常用的功能，将shp数据属性转成TXT和Excel
//转成txt
public static void ConvertTable2Txt(ITable pTable, string pFilePath)
{
int pIndex = 0;
string pStrLast = "";
string pTxtFile = System.IO.Path.Combine(pFilePath, (pTable as IDataset).Name + ".txt");
System.IO.FileStream pTxt1 = new System.IO.FileStream(pTxtFile, FileMode.Create);
StreamWriter pStrW = new StreamWriter(pTxt1);
int pFieldCount = pTable.Fields.FieldCount;
ICursor pCursor = pTable.Search(null, false);
IRow pRow = pCursor.NextRow();
//写入字段
for (int i = 0; i < pFieldCount; i++)
{
if (pTable.Fields.get_Field(i).Type != esriFieldType.esriFieldTypeGeometry)
{
pStrLast = pStrLast + "," + pTable.Fields.get_Field(i).Name;
}
}
pStrLast = pStrLast.Substring(1, pStrLast.Length - 1);
pStrW.WriteLine(pStrLast);
//写入值
while (pRow != null)
{
pStrLast = "";
pIndex++;
for (int i = 0; i < pFieldCount; i++)
{
if (pTable.Fields.get_Field(i).Type != esriFieldType.esriFieldTypeGeometry)
{
pStrLast = pStrLast+ "," + pRow.get_Value(i).ToString();
}
}
pStrLast =pStrLast.Substring(1, pStrLast.Length - 1);
pStrW.WriteLine(pStrLast);
if(pIndex==50)
{
pStrW.Flush();
pIndex=0;
}
pRow = pCursor.NextRow();
}
pStrW.Close();
}
//转成Excel
public static void ConvertTable2Excel(ITable pTable, string pFilePath)
{
int pIndex = 1;
string pTxtFile = System.IO.Path.Combine(pFilePath, (pTable as IDataset).Name + ".xlsx");
int pFieldCount = pTable.Fields.FieldCount;
ICursor pCursor = pTable.Search(null, false);
IRow pRow = pCursor.NextRow();
//写入字段
Microsoft.Office.Interop.Excel.Application pExcel = new Microsoft.Office.Interop.Excel.Application();
pExcel.Workbooks.Add(true);
pExcel.Visible = false;
Workbook pWorKbook = pExcel.Workbooks[1];
Worksheet xSheet = (Microsoft.Office.Interop.Excel.Worksheet)pWorKbook.Worksheets[1];
xSheet.Name = (pTable as IDataset).Name;
xSheet.SaveAs(pTxtFile, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
//字段
for (int i = 0; i < pFieldCount; i++)
{
xSheet.Cells[1, i + 1] = pTable.Fields.get_Field(i).Name;
}
//写入值
while (pRow != null)
{
pIndex++;
for (int i = 0; i < pFieldCount; i++)
{
xSheet.Cells[pIndex, i + 1] = pRow.get_Value(i).ToString();
}
pRow = pCursor.NextRow();
}
pWorKbook.Save();
pExcel.Quit();
}
