如何更改这些函数以返回字符串

问题描述：

foreach (var item in projectToWrite)
            {
                // Create an output file



                StringBuilder builder = new StringBuilder();
                msbuildFile.WriteLine(GetMSBuildFileHeader());
                msbuildFile.WriteLine(GetMSBuildFileItem(item, compilerOutputPath));


               // Add the Details
                if (item.Type == ProjectTypes.CPP)
                {

                 //WriteBuildFileFooterCPP(msbuildFile);
                    WriteBuildFileFooterCPP(msbuildFile);

                }

                else if (item.Type == ProjectTypes.Cs)
                {

                    //builder.Append(ProjectTypes.Cs);
                    WriteBuildFileFooterCS(msbuildFile);
                }
                else if (item.Type == ProjectTypes.VB)
                {
                  //builder.Append(ProjectTypes.VB);
                    WriteBuildFileFooterVB(msbuildFile);
                }


                msbuildFile.WriteLine(GetMSBuildFileFooter());


            }

            msbuildFile.Flush();
            msbuildFile.Close();
        }

用AppendLine指令替换WriteLines:

Replace the WriteLines with AppendLine instructions:

StringBuilder builder = new StringBuilder();
foreach (var item in projectToWrite)
{
    // Create an output file
    builder.AppendLine(GetMSBuildFileHeader());
    builder.AppendLine(GetMSBuildFileItem(item, compilerOutputPath));

以此类推.
注意:我将字符串生成器移到了循环之外，因此它会为所有字符串组装数据.

然后，最后:

And so forth.
NOTE: I moved the string builder outside the loop, so it assembles data for all strings.

Then, at the end:

return builder.ToString();

如果我正在阅读正确无误，在我看来，您只需要取消注释字符串生成器的附加行，然后将此循环放入返回字符串的函数中-您的最后一行将是

If I''m reading this correctly then it seems to me that you just need to uncomment your string builder append lines and put this loop into a function that returns a string - your last line would then be

return builder.ToString()
