C#使用Spire.Doc Word for .Net讀寫Word

之前對Excel或Word文檔操做都使用微軟的COM組件Microsoft Word 15.0 object library。

可是這種方式必需要求服務器上安裝Office，並且會出現讀寫操做完成後未成功釋放資源的狀況。

還有使用NPOI的方式，能夠在沒有安裝Office的狀況下對Word或Excel文檔進行讀寫操做，可是面對複雜的需求，仍是顯得無能爲力。

因而出現了一些其餘的API庫，如Spire.Doc和Aspose，不但能夠很好地讀寫操做Office文檔，並且能夠輕鬆實現PDF等文檔格式的轉換。

Spire.Doc支持JAVA和C#開發語言。咱們能夠從官網下載到。

Document document = new Document();
Section section = document.AddSection();
ShowProgressBar(); //顯示進度條
for (int i = 0; i < dsSpInfo.Tables[0].Rows.Count; i++)
{
       GenerateWord(document,section, dsSpInfo.Tables[0], dsQiandi.Tables[0], dsBaocun.Tables[0],i); //生成Word文檔
}
section.AddColumn(550f, 50f);  //添加分欄，參數爲分欄寬度
section.AddColumn(550f, 50f);
section.MakeColumnsSameWidth();
string s = Guid.NewGuid().ToString("N") + ".docx";
document.SaveToFile(@"temp\" + s, FileFormat.Docx);
document.Close();
System.Diagnostics.Process.Start(@"temp\" + s);

private void GenerateWord(Document document,Section section,DataTable dtSpInfo, DataTable dtQiandi, DataTable dtBaocun,int index)

      Paragraph pFamily = section.AddParagraph();   //添加段落
      AddTextRange(section, pFamily, cfamily, 14, true, "黑體", Spire.Doc.Documents.HorizontalAlignment.Center);
       AddTextRange(section, pFamily, family, 14, true, "宋體", Spire.Doc.Documents.HorizontalAlignment.Center);

          }

         for (int r = 0; r < arrQiandiData.Length; r++) //生成表體

                 }
            }
       }
}

須要注意的是，Spire.Doc是收費軟件，若是超過了免費版生成表格的數量（好像是25個），就要收取費用。不然會在生成的文檔的第一頁上方中添加廣告。
