IronXL 完全支持 .NET Standard库、核心应用程序、.NET 5 和 .NET 6 项目的 AWS Lambda 函数。

要为 Visual Studio 添加 AWS Toolkit，请点击此链接：在 Visual Studio 的 AWS Toolkit 中使用 AWS Lambda 模板。

在 Visual Studio 中安装 AWS Toolkit 后，即可创建 AWS Lambda 函数项目。您可以通过此链接学习如何使用 Visual Studio 创建 AWS Lambda 函数项目。

AWS Lambda 函数代码示例

创建新的 AWS Lambda 函数项目后，您可以尝试以下代码片段：

using System;
using Amazon.Lambda.Core;
using IronXL;

// Ensure this attribute targets your Lambda function
[assembly: LambdaSerializer(typeof(Amazon.Lambda.Serialization.Json.JsonSerializer))]

namespace AWSLambdaIronXL
{
    public class Function
    {
        /// <summary>
        /// A simple function that takes a string input and processes it using IronXL.
        /// This specific example creates a new Excel workbook and fills cells with labeled values.
        /// </summary>
        /// <param name="input">The string input for the function</param>
        /// <param name="context">The Lambda context</param>
        /// <returns>A Base64 string representation of the Excel file</returns>
        public string FunctionHandler(string input, ILambdaContext context)
        {
            // Create a new workbook with ExcelFileFormat.XLS
            WorkBook workBook = WorkBook.Create(ExcelFileFormat.XLS);

            // Create a new worksheet named "new_sheet"
            var newSheet = workBook.CreateWorkSheet("new_sheet");

            string columnNames = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
            foreach (char col in columnNames)
            {
                for (int row = 1; row <= 50; row++)
                {
                    // Construct cell name and fill it with data
                    var cellName = $"{col}{row}";
                    newSheet[cellName].Value = $"Cell: {cellName}";
                }
            }

            // Convert the entire workbook to a byte array and then to a Base64 string
            return Convert.ToBase64String(workBook.ToByteArray());
        }
    }
}

using System;
using Amazon.Lambda.Core;
using IronXL;

// Ensure this attribute targets your Lambda function
[assembly: LambdaSerializer(typeof(Amazon.Lambda.Serialization.Json.JsonSerializer))]

namespace AWSLambdaIronXL
{
    public class Function
    {
        /// <summary>

        /// This specific example creates a new Excel workbook and fills cells with labeled values.
        /// </summary>
        /// <param name="input">The string input for the function</param>
        /// <param name="context">The Lambda context</param>
        /// <returns>A Base64 string representation of the Excel file</returns>
        public string FunctionHandler(string input, ILambdaContext context)
        {
            // Create a new workbook with ExcelFileFormat.XLS
            WorkBook workBook = WorkBook.Create(ExcelFileFormat.XLS);

            // Create a new worksheet named "new_sheet"
            var newSheet = workBook.CreateWorkSheet("new_sheet");

            string columnNames = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
            foreach (char col in columnNames)
            {
                for (int row = 1; row <= 50; row++)
                {
                    // Construct cell name and fill it with data
                    var cellName = $"{col}{row}";
                    newSheet[cellName].Value = $"Cell: {cellName}";
                }
            }

            // Convert the entire workbook to a byte array and then to a Base64 string
            return Convert.ToBase64String(workBook.ToByteArray());
        }
    }
}
