However, the simple and generous background can make the document look more delicate and beautiful , So as to achieve a different visual effect . This article will be divided into three cases to introduce Word Add background , A solid background is added 、 Gradient background and picture background . attach C#/VB.NET Code , There is a need for reference .

Program environment

In this test , Introduce... Into the program

Free Spire.Docfor .NET

. Can be referenced by  Spire.Doc.dll file ：

Method 1

： take Free Spire.Doc for .NET Download to local , decompression , install . After installation , Find the installation path BIN In folder  Spire.Doc.dll. And then in Visual Studio Open in “ Solution explorer ”, Right click “ quote ”,“ Add reference ”, The local path BIN Under folder dll Add a reference to the program .

Method 2：

adopt

NuGet

install . This can be done by 2 Methods of installation ：

（1） Can be in Visual Studio Open in “ Solution explorer ”, Right click “ quote ”,“ management NuGet package ”, And then the search “Free Spire.Doc”, Click on “ install ”. Wait for the program installation to complete .

（2） Copy the following to PM Console installation .

Install-Package FreeSpire.Doc -Version 10.2.0

One 、 Set a solid background

Specific steps and codes

•    Create a Document Class object , Concurrent loading Word file .

•    adopt Document.Background.Type Property to set the background fill mode of the document to color fill .

•   adopt Document.Background.Color Property to set the background color .

•    use Document.SaveToFile（） Method to save a document .

【C#】

using System;
using System.Collections.Generic;
using System.ComponentModel;
using Spire.Doc;
using System.Drawing;

namespace AddBackground
{
 class Program
 {
 static void Main(string[] args)
 {
 // Create a Document Class object , And load Word file
 Document document = new Document();
 document.LoadFromFile(@"NewSample1.docx");

 // Set the background fill mode of the document to color fill
 document.Background.Type = Spire.Doc.Documents.BackgroundType.Color;

 // Set the background color
 document.Background.Color = Color.MistyRose;

 // Save and open the document
 document.SaveToFile("PureBackground.docx", FileFormat.Docx2013);
 System.Diagnostics.Process.Start("PureBackground.docx");
 }
 }
}

 document.LoadFromFile("NewSample1.docx")
 ' Set the background fill mode of the document to color fill
 document.Background.Type = Spire.Doc.Documents.BackgroundType.Color
 ' Set the background color

Two 、 Set gradient background

Specific steps and codes

•   Create a new instance document and use
  Document.LoadFromFile（） Method to load the instance document .

• adopt Document.Background.Type Property to set the gradient background type .

• adopt BackgroundGradient.Color1 Property to set the first gradient color .

• adopt BackgroundGradient.Color2 Property to set the second gradient color .

• adopt BackgroundGradient.ShadingVariant Property to set the shadow style and gradient effect

•   use
  Document.SaveToFile（） Method to save a document .

[C#]

using System.Drawing;
using System.Text;
using Spire.Doc;
using Spire.Doc.Documents;

namespace SetGradientBackground
{
 public partial class Form1 : Form
 {
 public Form1()
 {
 InitializeComponent();
 }

 private void button1_Click(object sender, EventArgs e)
 {
 // establish Word file .
 Document document = new Document();

 // Load instance document .
 document.LoadFromFile("NewSample1.docx");

 // Set the gradient background type .
 document.Background.Type = BackgroundType.Gradient;
 BackgroundGradient Test = document.Background.Gradient;

 // Set gradient color .
 Test.Color1 = Color.White;
 Test.Color2 = Color.LightBlue;

 //  Set shadow style and gradient effect .
 Test.ShadingVariant = GradientShadingVariant.ShadingDown;
 Test.ShadingStyle = GradientShadingStyle.Horizontal;

 String result = "Result-SetGradientBackground.docx";

 // Save the document .
 document.SaveToFile(result, FileFormat.Docx2013);
 }
 }
}

 ' establish Word file .
 Dim document As Document = New Document
 ' Load instance document .
 document.LoadFromFile("..\..\..\..\..\..\Data\Template_Docx_2.docx")
 ' Set the gradient background type .
 document.Background.Type = BackgroundType.Gradient
 Dim Test As BackgroundGradient = document.Background.Gradient
 ' Set the color 1 For the background , Color 2 For gradient .
 Test.Color1 = Color.White
 Test.Color2 = Color.LightBlue
 '  Set shadow style and gradient effect .
 Test.ShadingVariant = GradientShadingVariant.ShadingDown
 Test.ShadingStyle = GradientShadingStyle.Horizontal
 Dim result As String = "Result-SetGradientBackground.docx"
 ' Save the document .
 document.SaveToFile(result, FileFormat.Docx2013)
 End Sub
 End Class
End Namespace

3、 ... and 、 Set picture background

Specific steps and codes

•    Create and load sample documents

•    adopt Document.Background.Type Property to set the background picture type

•   adopt Document.Background.Picture Property to set the background picture

•    use Document.SaveToFile（） Method to save a document

using System.Drawing;
using System.Text;
using Spire.Doc;
using Spire.Doc.Documents;

namespace SetImageBackground
{
 class Program
 {
 static void Main(string[] args)
 {
 // Load the document
 Document document = new Document("NewSample1.docx");

 // Set the background picture type .
 document.Background.Type = BackgroundType.Picture;

 // Set the background image
 document.Background.Picture = Image.FromFile("Background.png");

 // Save the document .
 document.SaveToFile("ImageBackground.docx", FileFormat.Docx);


 }
 }
}

 Private Shared Sub Main(ByVal args() As String)
 ' load Word file
 Dim document As Document = New Document("Template.docx")
 ' Set the background picture type .
 document.Background.Type = BackgroundType.Picture
 ' Set the background image
 document.Background.Picture = Image.FromFile("Background.png")
 ' Save the document .
 document.SaveToFile("ImageBackground.docx", FileFormat.Docx)
 End Sub
 End Class
End Namespace

matters needing attention :

 

The document path generated in the code is VS programmatic Debug route , File paths can also be customized to other paths .
