例子

展示如何使用上下文通过一行代码转换文档。

string doc = MyDir + "Big document.docx";

Converter.Create(new ConverterContext())
    .From(doc)
    .To(ArtifactsDir + "LowCode.ConvertContext.1.pdf")
    .Execute();

Converter.Create(new ConverterContext())
    .From(doc)
    .To(ArtifactsDir + "LowCode.ConvertContext.2.pdf", SaveFormat.Rtf)
    .Execute();

OoxmlSaveOptions saveOptions = new OoxmlSaveOptions { Password = "Aspose.Words" };
LoadOptions loadOptions = new LoadOptions() { IgnoreOleData = true };
Converter.Create(new ConverterContext())
    .From(doc, loadOptions)
    .To(ArtifactsDir + "LowCode.ConvertContext.3.docx", saveOptions)
    .Execute();

Converter.Create(new ConverterContext())
    .From(doc)
    .To(ArtifactsDir + "LowCode.ConvertContext.4.png", new ImageSaveOptions(SaveFormat.Png))
    .Execute();

展示如何使用来自流的文档通过上下文从 DataTable 执行邮件合并操作。

// 有几种方法可以使用流中的文档从 DataTable 执行邮件合并操作：
DataTable dataTable = new DataTable();
dataTable.Columns.Add("FirstName");
dataTable.Columns.Add("Location");
dataTable.Columns.Add("SpecialCharsInName()");

DataRow dataRow = dataTable.Rows.Add(new string[] { "James Bond", "London", "Classified" });

using (FileStream streamIn = new FileStream(MyDir + "Mail merge.doc", FileMode.Open, FileAccess.Read))
{
    MailMergerContext mailMergerContext = new MailMergerContext();
    mailMergerContext.SetSimpleDataSource(dataTable);
    mailMergerContext.MailMergeOptions.TrimWhitespaces = true;

    using (FileStream streamOut = new FileStream(ArtifactsDir + "LowCode.MailMergeContextStreamDataTable.docx", FileMode.Create, FileAccess.ReadWrite))
        MailMerger.Create(mailMergerContext)
            .From(streamIn)
            .To(streamOut, SaveFormat.Docx)
            .Execute();
}

展示如何使用上下文通过一行代码从流中转换文档。

string doc = MyDir + "Document.docx";
using (FileStream streamIn = new FileStream(MyDir + "Big document.docx", FileMode.Open, FileAccess.Read))
{
    using (FileStream streamOut = new FileStream(ArtifactsDir + "LowCode.ConvertContextStream.1.docx", FileMode.Create, FileAccess.ReadWrite))
        Converter.Create(new ConverterContext())
            .From(streamIn)
            .To(streamOut, SaveFormat.Rtf)
            .Execute();

    OoxmlSaveOptions saveOptions = new OoxmlSaveOptions { Password = "Aspose.Words" };
    LoadOptions loadOptions = new LoadOptions() { IgnoreOleData = true };
    using (FileStream streamOut = new FileStream(ArtifactsDir + "LowCode.ConvertContextStream.2.docx", FileMode.Create, FileAccess.ReadWrite))
        Converter.Create(new ConverterContext())
            .From(streamIn, loadOptions)
            .To(streamOut, saveOptions)
            .Execute();

    List<Stream> pages = new List<Stream>();
    Converter.Create(new ConverterContext())
        .From(doc)
        .To(pages, new ImageSaveOptions(SaveFormat.Png))
        .Execute();
}

展示如何使用上下文将文档合并为单个输出文档。

//合并文档有几种方法：
string inputDoc1 = MyDir + "Big document.docx";
string inputDoc2 = MyDir + "Tables.docx";

Merger.Create(new MergerContext() { MergeFormatMode = MergeFormatMode.KeepSourceFormatting })
    .From(inputDoc1)
    .From(inputDoc2)
    .To(ArtifactsDir + "LowCode.MergeContextDocuments.1.docx")
    .Execute();

LoadOptions firstLoadOptions = new LoadOptions() { IgnoreOleData = true };
LoadOptions secondLoadOptions = new LoadOptions() { IgnoreOleData = false };
Merger.Create(new MergerContext() { MergeFormatMode = MergeFormatMode.KeepSourceFormatting })
    .From(inputDoc1, firstLoadOptions)
    .From(inputDoc2, secondLoadOptions)
    .To(ArtifactsDir + "LowCode.MergeContextDocuments.2.docx", SaveFormat.Docx)
    .Execute();

OoxmlSaveOptions saveOptions = new OoxmlSaveOptions { Password = "Aspose.Words" };
Merger.Create(new MergerContext() { MergeFormatMode = MergeFormatMode.KeepSourceFormatting })
    .From(inputDoc1)
    .From(inputDoc2)
    .To(ArtifactsDir + "LowCode.MergeContextDocuments.3.docx", saveOptions)
    .Execute();

//合并文档有几种方法：
string inputDoc1 = MyDir + "Big document.docx";
string inputDoc2 = MyDir + "Tables.docx";

using (FileStream firstStreamIn = new FileStream(MyDir + "Big document.docx", FileMode.Open, FileAccess.Read))
{
    using (FileStream secondStreamIn = new FileStream(MyDir + "Tables.docx", FileMode.Open, FileAccess.Read))

            .From(firstStreamIn)
            .From(secondStreamIn)
            .To(streamOut, saveOptions)
