如何根据现有列名更新文件夹中的多个文件名？ [英] How to update multiple file name from a folder based on existing column name?

问题描述

我有一个包含五个5列的表，包括没有扩展名的文件名。我想从一个文件夹将filename.pdf更新为gridview中的所有文件



在从grid文件夹更新gridview中的fileNameWithExtension之前我想将文件名与FName列匹配，如果然后将文件名更新为相应的文件名



表是：

 Column1 Column2 Column3 Fname FnameWithExtension 
 abv value2 value3 filename 
 abv value7 value8 filename1 

预期结果：

 Column1 Column2 Column3 Fname FnameWithExtension 
 abv value2 value3 filename filename.pdf 
 abv value7 value8 filename1 filename1.pdf 

使用此代码绑定gridvew但无法绑定相应的现有文件名



< pre lang =cs> protected void BindGridview（）
{
string strpath = @ E：\Internet Tips \;
string [] folders = Directory.GetFiles（strpath， *，SearchOption.AllDirectories）;
gvDetails.DataSource = folders;
gvDetails.DataBind（）;
}

I have a table with five 5 column including file name without extension. I want to update filename.pdf to all files in gridview from a folder

Before updating the fileNameWithExtension in gridview from folder I want to match file name with FName Column, If exist then update file name to corresponding filename

Table is:

Column1   Column2 Column3  Fname     FnameWithExtension
 abv      value2  value3  filename  
 abv      value7  value8  filename1  

Expected result:

Column1 Column2 Column3 Fname     FnameWithExtension
abv      value2  value3 filename  filename.pdf
abv      value7  value8 filename1  filename1.pdf

Using this code to bind the gridvew but not able to bind on corresponding existing File name

protected void BindGridview()
{
string strpath = @"E:\Internet Tips\";
string[] folders = Directory.GetFiles(strpath, "*", SearchOption.AllDirectories);
gvDetails.DataSource = folders;
gvDetails.DataBind();
}
