Question

string url = HttpUtility.HtmlAttributeEncode("https://site.sharepoint.com/sites/Project/Shared%20Documents/ExcelSheet.xlsx");

        Excel.Application xlApp = new Excel.Application();
        Excel.Workbook xlWorkbook = xlApp.Workbooks.Open(url):

这会提示我输入电子邮件（用户名）和密码，我知道我可以传递密码，但是如何在其中获取电子邮件（用户名）。

我还保存了SharpePoint凭据，我尝试使用SharepointClient进行尝试，但是我可以下载该文件，但我不知道如何将其转换为Excel工作簿以遍历单元格。 / p>

ClientContext context = new ClientContext("https://site.sharepoint.com/sites/Project/"):          
SecureString passWord = new SecureString();

 context.Credentials = new SharePointOnlineCredentials(password)

干杯！

Answer 1

我建议使用Excel Interop而不是Excel Services REST API，它可以读取excel数据，而无需依赖外部或第三方库。

示例

以下示例演示了如何从存储在SharePoint Online Documents库中的Financial Sample.xlsx示例excel文件中读取工作簿数据

var credentials = GetCredentials(userName, password);
var client = new ExcelClient(webUrl, credentials);
var data = client.ReadTable("Shared Documents/Financial Sample.xlsx", "Sheet1","A1", "P500");
JObject table = JObject.Parse(data);
int idx = 0;
foreach(var row in table["rows"])
{
     if(idx == 0)
     {
        //skip header
     }
     else
     {
        //get cell values
        var segment = row[0]["v"] as JValue;
        var country = row[1]["v"] as JValue;
        Console.WriteLine("Segment: {0}, Country: {1}", segment.Value,country.Value);
     }
     idx++;
}

其中

WebClient class用于消费Excel Services REST

public class ExcelClient : WebClient
{

    public ExcelClient(string webUrl, ICredentials credentials)
    {
        BaseAddress = webUrl;
        Credentials = credentials;
        Headers.Add("X-FORMS_BASED_AUTH_ACCEPTED", "f");
    }

    public string ReadTable(string fileUrl, string sheetName, string cellStart,string cellEnd, string format="json")
    {

        var endpointUrl = BaseAddress + string.Format("/_vti_bin/ExcelRest.aspx/{0}/Model/Ranges('{1}!{2}|{3}')?$format={4}", fileUrl,sheetName,cellStart,cellEnd,format);
        return DownloadString(endpointUrl);
    }

}

和SharePointOnlineCredentials class通过用户凭据访问SharePoint Online资源

static ICredentials GetCredentials(string userName, string password)
{
    var securePassword = new SecureString();
    foreach (var c in password)
    {
        securePassword.AppendChar(c);
    }
    return new SharePointOnlineCredentials(userName, securePassword);
}

结果
